摘要: High throughput architecture of an encoder and a decoder for quasi-cyclic low-density parity-check (LDPC) code is proposed. A new systematic encoding method carried out by polynomial manipulation. The proposed architecture, where the check-node process split into two processes so that memory access becomes column-wise, enables overlapped message-passing any matrix. hardware utilizing structure does not require complex multiplexers. Hardware employing (1440,1344) LDPC designed high millimeter wave application evaluated using 65 nm CMOS technology. gate count 3 Gbps 6 2.5 k 3.1 k, respectively, 8 iterations 304 409 respectively. bit-error rate 10-6 obtained at Eb/N0 5.9 dB, estimated power consumption 58 mW 86 Gbps.
