Abstract
The present invention provides a method and apparatus (,) for iteratively decoding data which has been encoded with contatenated codes. The apparatus (,) includes pipelined and cascaded decoder processors (,and,) connected to a multiple block memory device (,), through a multiplexing and data control block (,). A data decision element (,) is provided for generating decoded output data. The method includes receiving encoded data (,) while data already received is processed iteratively by decoder processors in a pipelined fashion. Decoder processors are designated to perform particular iterations (,) of an iterative decoding process which are performed simultaneously. As a decoder processor completes processing its designated iteration on a block of data, the decoder processor outputs decoding information (,) to the decoding processor designated to perform the subsequent iteration. Upon completion of all iterations for a block of data, the method includes generating output (,) consisting of the decoded data block. The method provides that once processing is complete on a data block, the memory block is made available (,) for the storing of new encoded input data.
