一种多载波跳频水声通信系统的级联码方案

A Concatenated Correct Code Scheme of Underwater Communication System Based on OFDM and FH

充分利用多载波跳频水声通信系统的信号特点,提出一种适合系统的级联码方案,给出了相应的编译码结构和算法。通过合理使用交织器,编码方案可以提供较好的纠错能力。

Based on signal characteristics of OFDM（Orthogonal Frequency Division Multiplexing） and FH（Frequency Hopping） underwater communication system, a system concatenated correct code .scheme is proposed. Structures and algorithms of encoder and decoder are given. With interleaver, the scheme provides excellent error code correction ability.
