Anti-jamming partially regular LDPC codes for follower jamming with Rayleigh block fading in frequency hopping spread spectrum

Frequency hopping spread spectrum is widely used for military communication. Anti-jamming scheme for the system has been one of the main topics for a long time. This paper introduces follower jamming model with random dwell time and block fading environment with M-ary frequency shift keying (MFSK) modulation. For coding perspective, new low density parity check (LDPC) codes against follower jamming are proposed. To optimize codes over jamming environment, the partially regular structure and the corresponding density evolution are used. Simulation results show that the proposed codes outperform those of IEEE 802.16e standard in the presence of follower noise jamming.
