Apparatus of multi-stage network for iterative decoding and method thereof
An apparatus and method of multi-stage network for iterative network are disclosed. The apparatus has M stages, and each stage uses N multiplexers to transmit N codeword partitions simultaneously. Every starting terminal, either the output port of memories, soft-in soft-out decoders, or multiplexers, has two paths to couple with two different multiplexers at next stage. One path connects the source to the first data port of one multiplexer; the other connects the source to the second data port of another multiplexer. The two multiplexers will be controlled with the same 1-bit signal, so each source has only one valid path to next stage. The invention can guarantee that the transmission of N data blocks is free from contention.
