Abstract: The invention encompasses several improved Turbo Codes Decoder method and apparatus to provide a more suitable, practical and simpler method for implementing a Turbo Codes Decoder in ASIC or DSP codes. (1) Two Parallel Turbo Codes Decoder blocks (40A & 40B) to compute soft-decoded data RXDa, RXDb from two different received path. (2) Two pipelined Log-MAP decoders (A42 & B44) are used for iterative decoding received data. (3) A Sliding Window of block N data are used on the input memory for pipeline operations. (4) The output Block N Data from the first decoder A are stored in the RAM memory A, and the second decoder B stores output data in the RAM memory B while the decoder B decodes block N data from RAM memory A at the same clock cycle. (5) Log-Map decoders are simpler to implement and are low-power consumption. (6) Pipelined log-Map decoder’s architecture provides high-speed data throughout, one output per clock cycle.
