The quasi-cyclic low-density parity-check (QC-LDPC) codes have attracted much attention in space communication systems. However, the decoders are still difficult to be applied in practice for their large area and high memory requirements. Moreover, the clock cycles for the input and output interfaces can not be ignored due to the I/O resource is also limited on this occasion, which influences the throughput improvement significantly. This paper presents a parallel pipelined decoder architecture… CONTINUE READING
