摘要: 该文基于短波跳频(FH)系统的特点,对短波跳频系统中分组 Turbo码的联合上界进行了分析和推导,给出了该编码在阻塞干扰存在的情况时平均误码率上限的数学表达式。并对分组 Turbo码在短波阻塞信道下的性能进行了数值模拟,结果表明:分组 Turbo码用于跳频系统时,在短波慢瑞利衰落的信道下,当信噪比为 20dB,信号阻塞比为 30dB时,可使系统的比特误码率由 10-3降为 10-5。Abstract: Based on the characteristics of Frequency Hopping(FH) system, the union-upper-bound of Block Turbo Codes (BTCs) in the short wave FH system is analyzed and deduced. The union-upper-bound equation for BTCs is given out in the barrage jamming. The numerical simulation of the BTCs is performed in short-wave jamming channel. When the signal-to-jamming ratio is 30dB, and signal-to-noise ratio is 20dB, simulation results show that using BTCs in FH system can reduce the bit error rate from 10-3 to 10-5.
