Embodiment

To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

Processing with former time-domain signal in the PCE2 technology transforms to frequency domain, makes the lifting of order of modulation reduce greatly demodulated complex degree and Effect on Performance, thereby has brought greater flexibility for the design of coding and modulation.Having now has 16 kinds of channel coding methods in the PCE2 technology, all corresponding a kind of modulation system of each channel coding method, and the corresponding two kinds of different character rates of data after handling according to this channel coding method and modulation system.For transmitting terminal; The symbolic number that different character rates is corresponding different; The symbolic number of different length is handled the inverse discrete Fourier transform IDFT module that can introduce different length, and the processing procedure of different burst structures, can increase the complexity of realization this moment.For example: the modulation system that channel coding method DBS-5 is corresponding is QPSK, and the result after coding and the modulation is sent according to high character rate HSR.Wherein, comprise TS (Training Sequence), CP (Cyclic Prefix), GP (Guard Period) and D (data symbol) several sections among the burst of existing PCE2.The total symbolic number of burst will satisfy 156.25 under the NSR; As an example; The concrete composition of the corresponding each several part symbolic number of total burst symbolic number can be N_NSR=58*2+26+6+8.25=156.25 under the NSR, and wherein, the TS number of characters is 26; The symbolic number of CP and GP is respectively 6 and 8.25, and the data symbol number is 116.And the total symbolic number of burst is 187.5 under the HSR; As an example; The concrete composition of the corresponding each several part symbolic number of total burst symbolic number can be N_HSR=69*2+31+8+10.5=187.5 under the HSR, and wherein, the TS number of characters is 31; The symbolic number of CP and GP is respectively 8 and 10.5, and the data symbol number is 138.It is understandable that the symbolic number of TS, CP, GP and data symbol number can change according to condition of different or coding and modulation in burst forms, but as long as all constituents symbolic number sum satisfies the total symbolic number of NSR, then send according to NSR; And all constituents symbolic number sum satisfies the HSR symbolic number, then sends according to HSR.

Need to prove; The down channel coding of existing EGPRS2 comprises the coding of USF (Uplink State Flag), the coding of head (Header), the coding of service data information (Data), coding and SB (the Stealing Bits of PAN (Piggy-backedAck/Nack); Also can write SF:Stealing Flag, steal bit) coding.Chnnel coding in the follow-up specification refers to the chnnel coding general name that comprises the each several part coding.Wherein the coding of SB is to distinguish a type of data in the chnnel coding source information, i.e. Header Type through the code word of certain-length.Because only corresponding a kind of the coded system of present a kind of Header Type, this just means that SB essence is to be used for distinguishing different header encoder modes.If identical Header Type has adopted the different coding mode, so also need different SB code words to distinguish.For the sake of simplicity, follow-up specification part SB also can write corresponding different Header Type.CPS (Coding and Puncturing Scheme indicator field) is a part in the header, is used for indicating chnnel coding and hole knockout.

To above-mentioned channel coding method, existing receiving terminal decode procedure is:

Determine the modulation system and the speed of data through modulation system and speed blind Detecting, and carry out corresponding demodulation;

Value through SB is judged the coded system of Header, carries out the decoding of Header;

The CPS domain information is judged chnnel coding and hole knockout among the Header that obtains through decoding;

Through the channel coding method of judging, respectively USF, Data and PAN are deciphered accordingly, thereby obtain all useful informations.

From the above, in the PCE2 technology, for receiving terminal, the coded system identifying comprises: modulation system and speed blind Detecting.As shown in Figure 1, (8PSK for NSR when modulation system and six kinds of combinations of transmission rate existence; QPSK for HSR; 16QAM for NSR; 16QAM for HSR; 32QAMfor NSR; 32QAM for HSR); So when carrying out modulation system and speed blind Detecting, receiving terminal can carry out the result that receives the differentiation of above-mentioned six kinds of combinations simultaneously, determines modulation system and speed according to differentiating the result; And carry out corresponding demodulation; Follow-up again according to SB identification with CPS identification judge the channel coding method that transmitting terminal adopts, finally the data after the demodulation are decoded, obtain the valid data information of transmitting terminal transmission.The identifying of above-mentioned channel coding method needs simultaneously character rate and modulation system to be carried out blind Detecting; Because modulation system is not limited to existing several kinds of modulation systems (as introducing new 64QAM modulation etc.); There are more kind in character rate and modulation mode combination; The process that causes the receiving terminal recognition coding like this, detection limit are greatly and complicated.

In the data processing method that the embodiment of the invention provided; Channel coding method and the modulation system of transmitting terminal through taking to have specific corresponding relation treated deal with data and carried out chnnel coding and modulation; Thereby the character rate with fixing sends pending data corresponding processing result, reduces the complexity in the transmitting terminal deal with data process with this; Simultaneously,,,, effectively like this reduced detection limit in the receiving encoding identifying, reduced complexity so when carrying out code identification, need not said result is carried out the speed blind Detecting because the result that receives has fixing character rate for receiving terminal.

The embodiment of the invention does not limit above-mentioned each component symbol number, and following examples only are the examples under specific T S, CP and GP length.

With under specific T S, CP and the GP length, it is example that the character rate of transmitting terminal is unified to ordinary symbol rate N SR below, that is: the data symbol of burst being counted unification is 116, and the data processing method that the embodiment of the invention provided is introduced.Because in the time period, character rate is directly decided by the number of symbols in the burst at fixing burst, therefore can the unification of character rate be reduced to the unification of burst internal symbol number.It is understandable that, also can the character rate of transmitting terminal is unified to high character rate HSR, that is: the data symbol of every burst being counted unification is 138.

At first introduce a kind of data processing method that the embodiment of the invention provides from the angle of transmitting terminal, as shown in Figure 2, said data processing method can may further comprise the steps:

Step S21, transmitting terminal obtain pending data, and the channel coding method of pending data;

Transmitting terminal in the present embodiment can be base station sub-system BSS; Base station sub-system BSS comprises: base station transceiver BTS and base station controller BSC; Base station transceiver BTS obtains pending data and channel coding method from base station controller BSC, treats deal with data then and carries out chnnel coding and modulation treatment., equally also can be the base station.

Step S22, according to channel coding method, and the corresponding relation of channel coding method of setting up in advance and modulation system is confirmed the modulation system of pending data;

Wherein, the corresponding relation of the said channel coding method of setting up in advance and modulation system be used to guarantee to treat deal with data encode with modulation treatment after result send according to the character rate of fixing.Step S23 treats deal with data according to channel coding method and carries out encoding process, and treats deal with data according to the modulation system of confirming and carry out modulation treatment;

Step S24, according to fixing character rate send treat deal with data encode and modulate after result.

Need to prove that the data after the above-mentioned coded modulation can also be passed through inverse discrete Fourier transform IDFT, increased processing such as CP, pulse shaping.

Further; In the foregoing description, be established as the pairing modulation system of channel coding method in the corresponding relation that guarantees channel coding method that the corresponding result of said pending data sends according to fixing character rate and modulation system in advance for than the high modulation system of the pairing modulation system exponent number of channel coding method in the corresponding relation of existing channel coded system and modulation system.

In existing PCE2 technology, channel coding method, modulation system, header type, SB bit etc. have specific corresponding relation, and example is as shown in table 1:

Table 1

Need to prove that in the above-mentioned table 1, character rate is with the result of actual symbol speed after with ordinary symbol speed normalizing.What DAS here and DBS represented is a kind of specific chnnel coding process, has comprised Header described above, Data, USF, SB, the process of these all part codings of PAN.Wherein, what D indicated is down channel, and A and B indicate the business of level-A and level-B respectively.

Can find out that by table 1 for modulation system QPSK, the modulation system higher than QPSK modulation system exponent number can be 8PSK; For modulation system 8PSK, the modulation system higher than modulation system 8PSK order of modulation is 16QAM.It is understandable that, can confirm that be not limited to a certain specific modulation system, for example: the modulation system higher than QPSK modulation system exponent number can be 8PSK, can also be 16QAM according to actual conditions than the modulation system that existing modulation system exponent number is high.

Treat deal with data; Utilize channel coding method and than the high modulation system of the pairing modulation system exponent number of channel coding method in the corresponding relation of existing channel coded system and modulation system encode and modulate after the result that obtains; With respect to utilize existing channel coding method and modulation system encode and modulate after the result that obtains; The frequency domain data symbolic number of every burst reduces, thereby realizes guaranteeing to meet through the result after coding and the modulation transmission condition of fixing character rate NSR.

Concrete frequency domain data symbolic number corresponding relation can be with reference to shown in the table 2:

Table 2

As shown in table 2; With coded system DBS-12 is example; Set up in advance in the corresponding relation that guarantees channel coding method that the corresponding result of said pending data is sent according to fixing character rate and modulation system; The modulation system that channel coding method DBS-12 is corresponding is 64QAM; After utilizing channel coding method and modulation system in this corresponding relation to encode and modulate, every burst data symbol number is limited in 116 in the result, thereby shows that this result can utilize fixing character rate NSR to send.When the data symbol number in the result less than 116 the time, the result after for example handling is 111, has also saved 5 data symbolic numbers with respect to 116; Data symbol number for saving can adopt following mode to adjust: keep the subcarrier number constant; 5 data symbolic numbers of saving are used for increasing the protection sideband, and the subcarrier number on the protection sideband can fill out 0, i.e. the gap carrier wave; Here can be called the padding filling symbol, its length is represented with L.When transmitting terminal sends result with fixing character rate NSR; Can be through the size of adjustment L; So that result satisfies the transmission condition of NSR speed, promptly under specific T S, CP and GP length, every burst data symbol number adjustment in the result is reached 116.

It is understandable that the corresponding relation shown in the table 2 only is an example, is not construed as limiting the invention.

Need to prove,, can satisfy the condition of sending according to fixing character rate owing under specific T S, CP and GP length, every burst data symbol number adjustment in the result is reached 116.Therefore, also can adjust the number of characters length of TS, CP and GP, to satisfy the condition that result can be sent according to mark-hold speed according to actual conditions.

Because the output information amount that the data symbol number is actually by chnnel coding among every burst decides; So also can be under the constant situation of TS, CP and GP number of characters; On the basis that utilizes the high modulation system of above-mentioned exponent number to modulate; Through revising coding output information amount, the data symbol number of every burst is adjusted into 116, satisfy the condition of sending result with ordinary symbol rate N SR.Therefore; When setting up the corresponding relation of channel coding method and modulation system; Consider from the angle that changes chnnel coding output information amount; Adopt the highly redundant coded system, the highly redundant coded system is: treat the output information amount that obtains behind the deal with data coding and be higher than the channel coding method according to the output information amount behind the coding of the channel coding method in the corresponding relation of existing channel coded system and modulation system.The data that transmitting terminal obtains after encoding according to above-mentioned highly redundant channel coding method; After utilizing the high modulation system of exponent number to modulate; The data symbol number of every burst is 116 in its result, then can realize the purpose that result is sent according to fixing character rate NSR.

In the result after the corresponding relation of the modulation system that highly redundant coded system and exponent number are high and chnnel coding and the modulation every burst data symbol count situation of change can be referring to shown in the table 3:

Table 3

As shown in table 3, need to prove that consider channel interleaving, the information bit after the chnnel coding need utilize 4 burst to carry here.Because former channel coding method DBS-5 sends with HSR, every burst data symbol number is 138, employing be the QPSK modulation, therefore the information bit behind the coding is a 138*2*4=1104 bit, wherein 2 modulates the bit number of every symbols carry for QPSK.For the result after guaranteeing to handle can send with NSR; Then every burst data symbol number need be reduced to 116; Consider the performance of chnnel coding, can adopt the data after the high modulation system of exponent number is carried coding here, for example choose 8PSK as the high modulation system of exponent number; Data behind the coding become the 116*3*4=1392 bit so, wherein 3 modulate the bit number of every symbols carry for 8PSK.For channel coding method DBS-5, the data behind its coding are 1104 bits, increase to 1392 in order to treat the information bit that obtains after deal with data is encoded; Adopt the mode of adjustment DBS-5 here; Make it have higher redundancy, through higher redundancy, the information bit after realization will be encoded increases to 1392; Can be with this adjusted, having more, the channel coding method of highly redundant is called DBS-5a.For other coded system by that analogy.

Under the situation that performance meets the demands; The modulation system that new channel coding method is corresponding also can be selected other mode, in every burst that the bit number behind the coding obtains according to expectation in the modulation system of data symbol number and selection the bit number of every symbols carry calculate.As, to the business of former DBS-5,, and select the 16QAM modulation to carry if expectation sends with NSR, the bit number behind the coding is 116*4*4=1856 so, then need take can bit number after the pending digital coding be satisfied is 1856 new channel coding method.

It is understandable that the corresponding relation shown in the table 3 only is an example, can not be construed as limiting the invention.

In like manner; Standing in the angle that changes chnnel coding output information amount considers; Channel coding method in the channel coding method of setting up in advance and the corresponding relation of modulation system can be low redundancy encoding mode; Low redundancy encoding mode is: treat the output information amount that obtains behind the deal with data coding and be lower than the coded system according to the output information amount behind the coding of the channel coding method in the corresponding relation of existing channel coded system and modulation system; Thereby make the information bit of modulating according to the modulation system in the corresponding relation of existing channel coded system and modulation system reduce, and then realize that utilizing the data symbol number of every burst in the result after this modulation system is modulated is 116.As shown in table 4:

Table 4

Referring to table 4; Business with former DBS-5 is an example, if the expectation transmission rate is NSR, and selects still to carry with QPSK; Bit number behind the coding is necessary for the 116*2*4=928 bit so, and the new coding that obtains 928 bits after pending data are encoded is called DBS-5b.Compare 1104 bits behind the original encoding, the redundancy of new channel coding method has reduced, and can be called low redundant coding.Along with the continuous development and the evolution of coding techniques, new coding techniques can satisfy performance requirement under low redundant situation.

It is understandable that the corresponding relation shown in the table 4 only is an example, can not be construed as limiting the invention.

Further, in the data handling procedure, according to said channel coding method said pending data are carried out comprising in the process of encoding process:

Set the preset value of the value of stealing bit SB in the said pending data channel coding for distributing for header encoder mode corresponding in the said channel coding method in advance.

Said SB value is used for the data of receiving terminal after to demodulation and carries out the differentiation of header encoder mode.

Need to prove; Above-mentioned set up in advance in the corresponding relation that guarantees channel coding method that the corresponding result of said pending data is sent according to fixing character rate and modulation system; The corresponding relation that not only comprises channel coding method and modulation system also comprises header encoder mode corresponding with channel coding method and the corresponding relation of SB etc.Header type as shown in table 1, that channel coding method is corresponding unique, the then corresponding multiple channel coding method of a kind of header type.Receiving terminal is when carrying out code identification, owing to there is different character rates, 8 complete 0, or 8 complete 1 SB value can be distinguished different types of header type.In the present embodiment; For set up in advance in the corresponding relation that guarantees channel coding method that the corresponding result of said pending data is sent according to fixing character rate and modulation system; Character rate is unified to be NSR, for receiving terminal under fixing character rate, still can distinguish the header type of result according to the value of SB; Under condition of different, the different header encoder modes that channel coding method is corresponding have different SB preset values.For example: DBS-5 and DBS-6; DAS-5, DAS-6 and DAS-7;

Identical modulation system, the corresponding a kind of header type kind of difference that above-mentioned two group coding modes are corresponding respectively so still can adopt the setting means of existing SB value, utilize original SB value to identify header type.

And for DAS-8, DAS-9, DBS-7, DBS-8, DBS-9; The modulation system that these coded systems are corresponding identical, but respectively corresponding three kinds of header type (header type4, header type7, header type8); 8 complete 0 and 8 complete 1 two kinds SB values can't be distinguished three kinds of header type in the prior art at this moment, thus need distribute new SB value for it, to distinguish different types of headert ype; Said SB value can be three kinds of 8 binary codes.

For DAS-10, DAS-11, DAS-12, DBS-10, DBS-11, DBS-12; Its situation with DAS-8, DAS-9, DBS-7, DBS-8, DBS-9 is similar; The modulation system that above-mentioned coded system is corresponding identical; But corresponding 4 kinds of header type (header type10, header type5, header type8, header type9), this moment, the SB value was four kinds of 8 binary codes according to above-mentioned thought.

In practical application; In order to make set SB value have certain fault-tolerance; Even if transmitting the back in channel, the data after guaranteeing to handle because disturb variation has taken place; Still can confirm its SB value through its differentiation is the mode of SB value immediate with it, so need to guarantee to have approximately equal and big as far as possible Hamming distance between each yard of SB value under the modulation system of the same race.

For example: for DAS-8, DAS-9, DBS-7, DBS-8, when the pairing header type of DBS-9 is provided with the SB value, can be with reference to like following table 5:

Channel coding method	Header?type	SB?bits
			DAS-8	header?type?4	1，1，0，0，1，0，0，0
DAS-9	header?type?4	1，1，0，0，1，0，0，0
			DBS-7	header?type?7	0，0，0，1，0，1，1，0
DBS-8	header?type?7	0，0，0，1，0，1，1，0
			DBS-9	header?type?8	1，1，1，1，1，1，1，1

Table 5

As shown in table 5, any two Hamming distance of SB value that is used for distinguishing header type for set three kinds of channel coding method is 5 or 6, and the value of the SB of different channels coding is placed on position unified among the burst.The corresponding relation of SB encoded radio and chnnel coding type is not limited to the example in the table 5, and as 0,0,0,0,0,0,0,0 SB coding also can correspond to DAS-8 and DAS-9, and 0,0,0,1,1,1,1,1 SB coding can correspond to DBS-7 and DBS-8; 1,1,1,0,0,0,1,1 SB coding can correspond to DBS-9.

And when for DAS-10, DAS-11, DAS-12, DBS-10, DBS-11, when the pairing header type of DBS-12 is provided with the SB value, can be with reference to like following table 6:

Channel coding method

?Header?type

SB?bits

DAS-10	header?type?10	0，0，0，1，0，1，1，0
			DAS-11	header?type?5	1，1，1，1，1，1，1，1
DAS-12	header?type?5	1，1，1，1，1，1，1，1
			DBS-10	header?type?8	1，1，0，0，1，0，0，0
DBS-11	header?type?9	0，0，1，0，0，0，0，1
			DBS-12	header?type?9	0，0，1，0，0，0，0，1

Table 6

As in the table 6, any two Hamming distance of SB value that is used for distinguishing header type for set four kinds of channel coding method is 5 or 6.

It is understandable that the setting of said SB value is not limited to shown in table 5 and the table 6, have approximately equal and big as far as possible Hamming distance between each SB value as long as satisfy.Same, the corresponding relation of SB encoded radio and chnnel coding type is not limited to the example in the table 5, as: 0,0,0,0,0,0,0,0 SB coding can correspond to DAS-10; 0,0,0,1,1,1,1,1 SB coding can correspond to DAS-11 and DAS-12; 1,1,1,0,0,0,1,1 SB coding can correspond to DBS-10; 1,1,1,1,1,1,0,0 SB coding can correspond to DBS-11 and DBS-12.

When the character rate of transmitting terminal to fix, after for example NSR sent said result, receiving terminal need not the speed of said result is carried out blind Detecting in the process of recognition coding mode, has effectively reduced detection limit, reduced detection complexity.From the receiving terminal angle, a kind of data processing method that the embodiment of the invention provided, as shown in Figure 3, can may further comprise the steps:

Step S31 receives the result that network side sends according to fixing character rate;

Step S32 according to said fixing character rate, determines the modulation system of the said result that receives through the modulation system blind Detecting;

Step S33, utilize said modulation system that said result is carried out demodulation.

Determine the modulation system of received result through the modulation system blind Detecting, said result is carried out demodulation, confirm the channel coding method of said result according to the data after said modulation system and the demodulation according to said modulation system.Receiving terminal is decoded according to the data of the channel coding method of confirming after to demodulation then, obtains the valid data information that transmitting terminal sends.

Further, the said fixing character rate of above-mentioned foundation, the process of modulation system that determines the said result that receives through the modulation system blind Detecting is specifically as shown in Figure 4, comprising:

Step S41 according to said fixing character rate, carries out the handling process of different modulating mode with said result respectively, obtains different result of flow;

Because the character rate of received result is fixed, so only need modulation system to be carried out blind Detecting according to this character rate.For the result of utilizing fixing character rate to send, it is 4 kinds that receiving terminal carries out the modulation system that the modulation system blind Detecting determined: 8PSK, 16QAM, 32QAM, 64QAM; So respectively carry out the differentiation of 4 kind modulation systems with said result this moment, obtain 4 and differentiate the result.

Step S42 utilizes preset criterion, and said result of flow is carried out analyzing and processing, confirms the modulation system of said result.

Wherein, said decision rule is a prior art, like maximum signal noise ratio principle, and can confirm according to actual conditions, does not introduce at this.

Further, the data after said modulation system of above-mentioned foundation and the demodulation confirm that the process of channel coding method of said result is as shown in Figure 5, comprising:

Step S51 according to the channel coding method of setting up in advance and the corresponding relation of modulation system, confirms the header type species number corresponding with said modulation system;

Step S52 judges whether corresponding unique header type of said modulation system, if then carry out S54; Otherwise, carry out S53;

Step S53 according to the SB value of the data carry after the said demodulation, confirms the header type that result is corresponding;

Receiving terminal is according to the preset channel coding method and the corresponding relation of modulation system, and the value of the SB that carries according to said result is determined the corresponding header type of result, carries out CPS then and discerns.

It is understandable that; Because there be certain interference in channel, set SB possibly receive channel disturbance and causes code value to change in the result, when differentiating; The SB value is confirmed as immediate SB value in the preset relation, and then determine corresponding header type.

Whether step S54, the corresponding header type of judgment processing result corresponding a kind of channel coding method, if, execution in step S55 then, if not, execution in step S56 then;
