摘要 LDPC码是目前发现的性能最好的纠错码,本文深入分析了采用LDPC纠错编码的快速跳频通信系统的实现方法,通过仿真说明了采用LDPC纠错编码的快速跳频通信系统和分集合并进行联合编码时,存在一种最优的组合,LDPC码有最佳的码率。仿真结果也表明采用LDPC纠错编码的快速跳频系统有良好的抗部分频带干扰的性能。 Nowadays,LDPC code is the best error-correcting code. The paper analysises the implementation of LDPC coded FFH/BFSK systems. From simulation,it shows that when joint-coding LDPC and diversity,there is a best choice and LDPC code has a best code rate. The results also show that LDPC coded FFH/BFSK systems have perfect performance of anti- partial-band jamming.
