Abstract :
The performance of an iterative decoding and noncoherent demodulating algorithm to suppress the multi-tone jamming (MTJ) in FH-CPM systems is studied in this paper. To reduce the complexity of the demodulator, an iterative tree search (ITS) method, based on Laurent decomposition, is exploited. And to enhance the reliability of the system, an iterative multi-tone jamming state information (MTJSI) estimation method is proposed in this paper. Simulation results demonstrate that the iterative detection algorithm combining with the MTJSI estimation method takes on good BER performance in the presence of MTJ on an additive white Gaussian noise channel.
