Encoding technology is an effective measure to combat jamming by taking advantage of encoding redundancy. Low-Density Parity-Check (LDPC) code, with excellent performance that is close to theory limit, has drawn an increasing attention in Frequency Hopping communication system. In this paper, the influence of phase offset is investigated for LDPC-SFH (slow frequency hopping) in Single-tone Interference (STI) and additive white Gaussian noise (AWGN) channels. In addition, the influences of code rate and code length are analyzed and examined, respectively. Simulation results show that the phase offset is a factor of system performance and the LDPC-SFH system can obtain excellent performance against STI and phase offset with the appropriate design.
