Fig. 5 shows the flow chart that is used for according to the preferred embodiment of the invention the implementation method of WCDMA receive direction transport channel data demultiplexing, comprises the steps:
Parameter configuration: all transmission channels are carried out TTI frame length, physical channel time slot format, effectively number, time slot format compression pattern, the transformat configuration of physical channel.Wherein the length of TTI frame is 10ms, 20ms, four kinds of configurations of 40ms, 80ms, if 10ms is configured to 0,20ms is configured to 1,40ms is configured to 2,80ms is configured to 3; Physical channel time slot, physical channel number and time slot format compression pattern are configured according to the regulation of 3GPP; Transformat is by coming afterwards configuration of TFCI decoding;
Transmission channel ordering: according to the TTI value of each transmission channel, eight transmission channels are sorted, in the default situation, order is transmission channel 0, transmission channel 1, up to transmission channel 7.When the configuration of each transmission channel TTI not simultaneously, before we were placed on the transmission channel of TTI maximum, the transmission channel of TTI minimum came at last.If the TTI frame length of two transmission channels is identical, transmission channel number little front, for example the TTI frame of transmission channel 0 and transmission channel 7 all is 10ms, transmission channel 0 comes transmission channel 7 fronts so;
Determine rate matching pattern: according to the data of each radio frames of the transformat of each transmission channel and physical channel, (the compression pattern by physical channel time slot format, effective physical channel number, time slot format is determined for TTI length and transformat configuration, realize according to the 3GPP agreement) determine the rate matching pattern of going of transmission channel, comprise punching rate matching and go bit repetition rate coupling, realize according to the 3GPP agreement; Pre-determine rate matching pattern in the preferred embodiment, then can guarantee going under the repetition rate match pattern, execution the above embodiment of the present invention provides data are merged is put into the technical scheme of carrying out the most afterwards.
Determine the byte length of transmission channel: determine initial address and the byte length of each transmission channel in RAM by TTI, transformat and the rate matching pattern of each transmission channel.For removing the repetition rate match pattern, determine the RAM memory length by the data volume behind the turbo coding, can draw according to transformat, the RAM byte that takies is tf_block* (tf_block_bit+CRC redundant bit)+12 * code_block, wherein tf_block is the number of transmission block, tf_block_bit is each transmission block Nepit number, and code_block is the encoding block number.Take the 384K business as example, suppose that the transmission block number is 1, the number of each piece is that 1000, CRC redundant bit number is 8, the encoding block number is 1 so, so the RAM byte that takies is 1020.For the rate matching pattern of going to punch, determine the RAM memory length according to the TTI of transmission channel and the data volume in each radio frames, byte length is F * H or F * G, F * H is selected in mapping for the fixed position, shine upon for variable position, select F * G, wherein F is the radio frames number of the TTI frame of transmission channel, H is that the DTX bit is removed (fixed position mapping) front byte number in the radio frames, and G is the byte number after the DTX bit removal (variable position mapping) in the radio frames.Be mapped as example with the fixed position, the radio frames number that comprises of supposing the TTI frame is that the byte number H of 8, one radio frames is 1000, so the byte degree of depth 8 * 1000=8000 of the RAM that takies of this transmission channel;
The ram space of transmission channel is determined: according to the byte length of transmission channel ordering and transmission channel, can determine the ram space of transmission channel.Number according to transmission channel is divided into the N part with RAM, ordering according to transmission channel is divided, suppose that 3 transmission channels are effective, ordering is transmission channel 0, transmission channel 1, transmission channel 2, so RAM is divided into 3 parts, transmission channel 0, transmission channel 1 and transmission channel 2 be corresponding first, second, and third part respectively, determines that according to the byte length of each transmission channel each transmission channel is in space that RAM takies.Suppose that transmission channel 0,1,2 byte length are respectively 1000,2000,3000 bytes, the ram space that takies of transmission channel 0 is 0 to 999 so, the ram space that transmission channel 1 takies is 1000 to 2999, and the ram space that transmission channel 3 takies is 3000 to 5999;
For the second time deinterleaving and physical channel merge: will merge from the data of a plurality of physical channels of RAKE, and carry out deinterleaving processing second time, realize with reference to the 3GPP agreement;
For the second time DTX deletion: the variable position mapped mode is carried out the DTX deletion action, realize with reference to the 3GPP agreement;
Transport channel data is decomposed: according to the byte length of a radio frames of each transmission channel, be written to successively in the ram region under each transmission channel finishing data after for the second time DTX deletion, transmission channel 0 is deposited according to ram space separately to the data of transmission channel 7;
For the first time deinterleaving: carry out the deinterleaving first time in the TTI frame of data to each transmission channel and process, after finishing merging, complete TTI frame data carry out the deinterleaving first time for going the punching rate matching pattern, implementation method realizes according to the 3GPP agreement, specific algorithm is seen 3GPP TS 25.212 agreements regulation, for removing the repetition rate match pattern, after each wireless frame data is come, carry out at once the deinterleaving first time and process;
Go the repetition rate coupling: go the repetition rate coupling to carry out the rate-matched processing according to the repetition rate matching algorithm of 3GPP TS 25.212 agreements exactly;
Go punching rate matching: the punching rate matching algorithm according to 3GPP TS 25.212 agreements carries out the rate-matched processing;
