PROJECT TITLE :

Two-Extra-Column Trellis Min–Max Decoder Architecture for Nonbinary LDPC Codes - 2017

ABSTRACT:

In this temporary, a unique two-extra-column trellis min-max algorithm and therefore the decoder architecture based mostly on solely the first minimum values are proposed for nonbinary low-density parity-check (NB-LDPC) codes. The algorithm greatly reduces the hardware complexity and improves the latency as well as the throughput of the proposed decoder design compared with the previous works. A layered decoder architecture primarily based on the proposed algorithm for (837, 726) NB-LDPC code over GF(32) is implemented with a 90-nm CMOS technology. The results show a decrease in the realm of twenty four.sixpercent for the check node unit and seventy five.vipercent for the full decoder with a throughput of 1.27 Gb/s. The proposed decoder provides a lower space and a higher potency compared with the state-of-the-art of high-rate NB-LDPC codes with high Galois-field order.
