摘要： A reconfigurable maximum a-posteriori probability (MAP) calculation circuit that reuses the arithmetic logic unit (ALU) hardware to calculate forward state metrics (alpha values), backward state metrics (beta values), and extrinsic information (lambda values) for the trellis associated with the MAP algorithm. The alpha, beta and lambda calculations may be performed by the same ALU hardware for both binary code (i.e., WCDMA mode) and duo-binary code (i.e, WiBro mode).

摘要： A decoding process for decoding a received block of N systematic binary data samples or N systematic duobinary data samples using a maximum a posteriori probability (MAP) decoding algorithm. The decoding process calculates a set of four log-likelihood values using the corresponding forward state metric, reverse state metric, and branch metric values for each of N/2 pairs of systematic binary data or each of N/2 pairs of duobinary data in the received block. The decoding process also calculates, for each set of four log-likelihood values a delta value corresponding to the difference between the largest and the second largest of the four log-likelihood values in each set. The decoding process repeats for at least a second iteration. The decoding process is stopped based on a plurality of delta values calculated during two consecutive iterations.

摘要： A method for operating a contention-free interleaver for channel coding is provided that includes generating a sub-table based on a data block size, N, and an offset vector, v, of length x and generating an interleave table based on the sub-table.

In addition, the sub-table may be generated based on the data block size and the offset vector by (i) rounding the data block size up to a nearest multiple of the length, x, of the offset vector to generate a modified block size, N′, and (ii) generating the sub-table of a size equal to N′/x.

摘要： A system for cyclic redundancy check (CRC) calculations with modulo-2 multiplication is disclosed for repetitive CRC computations that optimizes processing efficiency and maximizes capacity. The resulting system results in the use of relatively fewer logical gates and conserves on power. The system receives a message ({right arrow over (m)}) including a plurality of blocks ({right arrow over (b)}i) and a set of pre-computed coefficients ({right arrow over (β)}i). The system performs a modulo-2 multiply-accumulate operation on the message ({right arrow over (m)}) using the relationship given by: CRC ⁡ ( m → ) ≡ CRC ( ∑ i ⁢ b → i ⊗ β → i ) .
