Abstract

The research of Reed-Solomon code (RS) for slow frequency-hopping systems have been extensively studied in recent years. Previous studies has considered to combine error correction coding with image restoration techniques to improve anti-jamming capability for image transmission. Low-density parity check code (LDPC) has become popular because of its flexibility in codeword length and better performance than those of other codes. Therefore, in this paper, we propose a image transmission system which empolyed LDPC code to replace RS code under partial band noise jamming (PBNJ). Besides, we also propose a iterative decoding scheme which integrated the information after image process and the channel information. Simulation results show that the proposed system can effectively improve the quality of the received images.
