A system and method employing a modular decoder for decoding turbo and turbo-like codes in a communications network

摘要

A system and method for decoding encoded data is provided. A parser receives and parses the encoded data into data streams, with each of the data streams including a portion of said encoded data. A decoder decodes the data streams to provide decoded data which includes soft decision data. The decoder performs an decoding iteration on each of the data streams to provide the decoded data, and performs such decoding iterations based on additional information. The system and method alternatively can be configured without a parser, and can employ at least one soft decoder module and another decoder module. The soft decoder module performs multiple decoding iterations on the encoded data to provide soft decision data and the other decoded module decodes the encoded data based on the soft decision data to provide hard decoded data representative of a decoded condition of said encoded data and/or soft decision data.
