The conventional methodology for designing QC-LDPC decoders is applied for fixed configurations used in wire-less standards,and the supported largest expansion factor Z(the parallelism of the layered decoding)is a fixed number.In this paper,we study the circular-shifting net-work for decoding LDPC codes with arbitrary Z factor,especially for decoding large Z(Z>>P)codes,where P is the decoder parallelism.By buffering the P-length slices from the memory,and assembling the shifted slices in a fixed routine,the P-parallelism shift network can process Z-parallelism circular-shifting tasks.
