Abstract
A system and method are provided for parallel path turbo decoding in a portable wireless communications user terminal (UT). The method accepts a coded stream having a first order of information packets, and demultiplexes the coded stream into first coded and second coded information streams. The first coded stream is turbo decoded, generating a first decoded information stream. Likewise, the second coded stream is decoded to generate a second decoded information stream, asynchronously with respect to the first decoded stream. Then, the first and second decoded streams are combined into a combined stream having the first order of decoded information packets. The first and second decoded streams are combined by parallel buffering the first and second decoded streams, generating parallel-buffered decoded streams. Then, the parallel-buffered decoded streams are multiplexed to create a combined stream, which is stored in an output buffer.
