A BICM-MD-ID Scheme in FFH System for Combatting Partial-Band Interference
An iterative decoding scheme with diversity is proposed for LDPC coded FFH/MFSK system under partialband interference. The performance gain is obtained by softinformation 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.
