Performance Analysis of LDPC Coded SFH/BPSK in LFM Jamming

In this paper, we investigated the low density parity check (LDPC) coded performances of slow-frequency-hopped binary phase shift-keying (SFH/BPSK) systems in the presence linear frequency modulated (LFM) jamming. We investigated the effects of code rate, code length, the number of symbols per hop (SPH) and interleaver on the performance of the SFH/BPSK system with LFM jamming by numerical simulation. And the results suggest that there is good performance through designing the system reasonably.
