A technique to improve the performance of fixed-point TDMP decoding of QC-LDPC codes in the presence of SNR estimation error

Abstract

Most high-throughput, fixed-point processors offer at least two options for arithmetic operations: 8-bit arithmetic, and 16-bit arithmetic. The lower resolution provides higher computational throughput at the cost of poorer performance in many applications. We investigate the effect of the resolution of saturating, fixed-point arithmetic on the performance… (More)
