Comparison of channel codes in presence of pulsed jammers in TT&C links

Abstract

This paper compares different channel coding schemes, such as the short Low-Density Parity-Check (LDPC) proposed by NASA for TC applications, and Reed Solomon (RS) codes, in presence of pulsed jammers that causes burst errors. The burst error patterns are generated also considering the occurrence of cycle slips due to the pulsed jammers. Moreover, the effectiveness of introducing interleavers of different depths is investigated for both channel codes. The comparison shows that RS codes represent a robust solution in presence of pulsed jammers and they provide a better trade off performance/latency than short LDPC codes.
