Application of LDPC Codes over GF(q) to DFH Communication System

Abstract

This paper presents the design and performance of a LDPC-DFH technique. We apply the low-density parity-check codes over GF(q) to differential frequency hopping (DFH) communications system. Homogeneity and randomness of its frequency hopping sequences are analyzed. The structure and decode algorithm of LDPC-DFH system are proposed. Simulation results show LDPC-DFH system outperforms conventional DFH system and Turbo- DFH system.
