Abstract
An iterative decoding scheme with diversity is proposed for LDPC coded FFH/MFSK system under partial-band interference. The performance gain is obtained by soft-information exchange between demodulator and decoder. Extrinsic information transfer (EXIT) chart is employed to study the iterative procedure, which indicates that the convergence speed of the system is fast. The simulation results show the presented scheme outperforms traditional FFH/BFSK system, and the gain increases as the jamming probability increases. In addition, a moderate modulation order should be chose carefully in practical system.
