3. the dual decoding algorithm is realized.
In order to realize resource-sharing, present dual decoding algorithm similarity and principle difference are very little, and can only adopt alternative mode, and different business is handled, and effect is also not obvious.
4. use DSP to realize the decoding of the LTE standard of two-forty.
Current, particularly at the LTE standard, the realization of Turbo decoder all also is based on the DSP pure software and realizes that its performance, power consumption are compared pure hardware logic implementation itself and also had very big gap greatly.
Because all there is separately shortcoming in present various Turbo code decoders, for this reason, the present invention proposes a kind of novelty with improved coding/decoding method, decoder device and electronic equipment based on the Turbo code decoder.
＜the first embodiment 〉
Fig. 2 is the flow chart according to the coding/decoding method of first embodiment of the invention.
As shown in Figure 2, be applied in the decoder device in the mobile communication according to the coding/decoding method 100 of first embodiment of the invention, this decoder device comprises first decoder module and second decoder module.This coding/decoding method 100 comprises:
Step S101: the coded data Business Stream that receives input by a data passage.
In this step, receive the coded data Business Stream of input by a data passage (as the antenna in the portable terminal).For example, business refers to file transfer business, video traffic or speech business etc.This coded data Business Stream refer to from the base station or other mobile device sends, to the business datum data flow that the back obtains of encoding.As well known to those skilled in the art, in moving communicating field,, before sending, data need these data are carried out encoding process in order to guarantee the correct transmission of data, and this coding method for example comprises Turbo code coding, LDPC sign indicating number coding or the like.This coded data Business Stream can be the stream of a certain business datum, as the stream of speech business data, also can be the mixed flow of multiple business data, as the mixed flow of video traffic data and speech business data.
Step S102: the type of determining the coded data Business Stream of input.
In this step, determine the type of the coded data Business Stream of input, that is, the coded data Business Stream of determining this input is the coded data Business Stream of the first kind or the coded data Business Stream of second type.In the present invention, require to determine the type of this coded data Business Stream according to the error rate of business, wherein the error rate of primary sources Business Stream requires to be higher than the error rate requirement of secondary sources Business Stream.For example, will be defined as first kind business to the demanding business of the error rate (as file transfer, video traffic), therefore, the encoded data stream of file transfer can be as the example of this first kind coded data Business Stream.In addition, will be defined as the second class business to the less demanding business of the error rate (as speech business), therefore, the encoded data stream of speech business can be as the example of this second class coded data Business Stream.
Step S103: when the type of this coded data Business Stream is the first kind, this first kind coded data Business Stream is imported in this first decoder module, used this first decoder module that this first kind coded data Business Stream is decoded.
In this step, when the type of this coded data Business Stream is the first kind, the first kind coded data Business Stream of input is imported in first decoder module (that is, high bit-error requires decoder module), and used this first decoder module that this first kind coded data Business Stream is decoded.
Step S104: when the type of this coded data Business Stream is second time-like, this second class coded data Business Stream is imported this second decoder module (promptly, low error rate requires decoder module) in, use this second decoder module that this second class coded data Business Stream is decoded.
In addition, when this coded data Business Stream is the hybrid coding data traffic flow of the first kind and second class, first kind coded data Business Stream in this hybrid coding data traffic flow is imported in this first decoder module, use this first decoder module that this first kind coded data Business Stream is decoded, and the second class coded data Business Stream in this hybrid coding data traffic flow is imported in this second decoder module, used this second decoder module that this second class coded data Business Stream is decoded.
Particularly, with reference to figure 3, Fig. 3 is the realization block diagram of describing according to the coding/decoding method of first embodiment of the invention.In the figure, use two data buffer memorys 1 and 2 to carry out the data input, what this metadata cache 1 and 2 adopted is the table tennis storage mode, can replace storage, and each buffer memory all can offer data two passages of back.In the figure, the data flow of input comprises three kinds of situations:
1. when 1. the data flow of input comprises the first kind and the second class coded data Business Stream, the first kind coded data Business Stream of data flow in 1. (for example imported first decoder module, Turbo code decoder module based on the MAX-log-map decoding algorithm) in, and the second class coded data Business Stream of data flow in 1. imported in second decoder module Turbo code decoder module of SOVA decoding algorithm (for example, based on).Therefore, the decoding first kind coded data Business Stream and the second class coded data Business Stream of decoding in second decoder module in first decoder module can be realized synchronous high efficiency parallel decoding simultaneously.
2. when the data flow of input when 2. including only the second class coded data Business Stream, 2. data flow is imported in second decoder module Turbo code decoder module of SOVA decoding algorithm (for example, based on).Therefore, because by two-stage RAM buffered data, make when decoder decode, first RAM can read in data simultaneously, has saved the time of single reading certificate.
3. when the data flow of input when 3. including only first kind coded data Business Stream, 3. data flow is imported in first decoder module Turbo code decoder module of MAX-log-map decoding algorithm (for example, based on).Therefore, because by two-stage RAM buffered data, make when decoder decode, first RAM can read in data simultaneously, has saved the time of single reading certificate.
In addition, when the type of this coded data Business Stream is the first kind (that is, the coded data Business Stream that high bit-error requires), determine the pattern of this first kind coded data Business Stream, described pattern refers to the mobile communication standard of this coded data Business Stream.That is to say, for the coded data Business Stream that high bit-error requires, can also be by determining the pattern of coded data Business Stream, that is, the mobile communication standard of coded data Business Stream provides different Turbo code decoder module.For instance, when the coded data Business Stream of this high bit-error requirement is based on the data flow of LTE standard, uses and decode based on interlacing device and de-interlacing device and two RSC decoders of LTE standard.When the coded data Business Stream of this high bit-error requirement is based on the data flow of TD-SCDMA standard, uses and decode based on interlacing device and de-interlacing device and two RSC decoders of TD-SCDMA standard.
For this reason, this first decoder module based on first decoding algorithm (for example can comprise, the MAX-log-map decoding algorithm) one or more decoding submodules, for example at the decoding submodule of LTE standard, at the decoding submodule of TD-SCDMA standard, at submodule of WCDMA standard etc.According to the pattern of this first kind coded data Business Stream, that is, be based on which kind of mobile communication standard, select corresponding decoding submodule independently the first kind coded data Business Stream of input to be decoded.This mobile communication standard comprises the mobile communication standard at the 2G signal, comprise GPRS and GSM, described second mobile communication standard is the mobile communication standard at the 3G signal, comprise TD-SCDMA, CDMA2000, WCDMA and WiMAX, and described the 3rd mobile communication standard is the mobile communication standard at the 4G signal, comprises LTE and TD-LTE.In addition, can also responsively provide decoding submodule according to the development of mobile communication at the mobile communication standard of later appearance.
That is to say that each decoding submodule intactly comprises one group of interleaving/deinterleaving unit and two the RSC decoders that are used for specific mobile communication standard, this group interleaving/deinterleaving unit comprises an interleave unit and a deinterleaving unit.Therefore, each decoding submodule can be decoded to a kind of coded data Business Stream of pattern independently.
More preferably, this first decoder module based on first decoding algorithm (for example can comprise, the MAX-log-map decoding algorithm) one or more decoding submodules, for example at the decoding submodule of LTE standard, at the decoding submodule of TD-SCDMA standard, at submodule of WCDMA standard etc.In addition, according to the pattern of this first kind coded data Business Stream, a part of decoding unit in this decoding submodule is carried out multiplexing next first kind coded data Business Stream to input decode.
That is to say, this each decoding submodule comprises at least: be used for first mobile communication standard first group of interleaving/deinterleaving unit, be used for second group of interleaving/deinterleaving unit and two RSC decoders of second mobile communication standard, wherein first mobile communication standard is different with second mobile communication standard, and every group of interleaving/deinterleaving unit comprises an interleave unit and a deinterleaving unit.For example, with reference to the example among the figure 3, this decoding submodule comprises one group of interleaving/deinterleaving unit being used for the LTE standard, be used for one group of interleaving/deinterleaving unit and two RSC decoders 1 and 2 of TD-SCDMA standard.When decoding, according to the pattern of this first kind coded data Business Stream, select corresponding one group of interleaving/deinterleaving unit, and at least two RSC decoders are carried out multiplexing next first kind coded data Business Stream to input decode.For example, when the encoded data stream of input is the encoded data stream of LTE standard, connection is used for one group of interleaving/deinterleaving unit and two RSC decoders 1 and 2 of LTE standard, disconnect the one group of interleaving/deinterleaving unit that is used for the TD-SCDMA standard simultaneously, therefore, can decode to the encoded data stream based on the LTE standard of input.
In addition, when the input data be the second class coded data Business Stream (promptly, the coded data Business Stream that low error rate requires) time, this second decoder module based on second decoding algorithm (for example can comprise, based on the SOVA decoding algorithm) one or more decoding submodules, wherein each the decoding submodule independently to the input the second class coded data Business Stream decode.For example, when the coded data Business Stream of input be low error rate require the speech data Business Stream time, a decoding of this coded data Business Stream input submodule can be decoded to the speech data Business Stream of this input therein independently.
In addition, can also provide control module in the decoder device that uses this coding/decoding method, the storage decoding parametric is tabulated in this control module, for example carries out the number of times of iterative decoding.
Therefore, when this first kind coded data Business Stream being decoded by this first decoder module, length according to each packet in this first kind coded data Business Stream, from this decoding parametric tabulation, select corresponding decoding parametric, thereby each packet is decoded according to the decoding parametric of selecting.
Specifically, under the situation of 188 kinds of different types of data groupings, determine decoding characteristics according to different grouping length, under a common parameter condition, every kind of packet decoding is adopted different scheduling measures, as the number of times difference of iterative decoding, these differences all are that it is more efficient to compare fixed mode iterative decoding through the data of the test of practice.In addition, this decoding parametric tabulation can also use scene to select according to the different external worlds.
Because first decoder module requires to be higher than second decoder module for the error rate, therefore, this first decoder module requires than the high power of second decoder module.
In addition, at the decoding output, the data that decoding finishes are sent into the FIFO buffer memory earlier, and the FIFO degree of depth can be 8bit, 16bit, and 32bit etc. can determine according to subordinate's data format needs.And then with 8bit, the mode of 16bit or 32bit is exported to subordinate's code block cascade module together, has avoided the transmission means of 1bit serial.For example use the FIFO of the degree of depth, just can open the 8th clock cycle and receive the data that 8bit is wide, so just can save power consumption near 7/8 so that subordinate's code block cascade module was cut off the power supply in preceding 7 clock cycle as 8bit.Promptly utilize FIFO to provide convenience for the economize on electricity of subordinate's module.
Use above-mentioned decoder, can realize input pattern efficiently, according to the adaptive selection coding/decoding method of service needed, and buffer memory output, for subordinate's module provides the economize on electricity possibility.
Therefore,, can compatible multiple main flow move standard,, and can select coding/decoding method according to operation quality requirement as LTE and TD-SCDMA etc. according to the coding/decoding method of first embodiment of the invention.For single Business Stream, can use the coding/decoding method of low-power consumption to greatest extent, reduce the decoding power consumption to greatest extent; Can realize the high-speed parallel decoding for multi-business flow, improve the decoding throughput, adopt the way of output flexibly, for the economize on electricity of level module afterwards facilitates, the system for the low error rate as speech business requires can be suitable for well.
