摘要

A reconfigurable cyclic shifter is a key element of a QC-LDPC decoder, which is crucial for 5G communication systems. If a traditional reconfigurable cyclic shifter can only shift one input of variable size at a time, a traditional QC-LDPC decoder can only decode one codeword at a time as well. Part of the circuitry of the traditional QC-LDPC decoder inevitably stays in idle during the decoding pr...
