| 摘 要： | 针对FFH/MFSK通信系统的特点,推导了在赖斯衰落信道下,多音干扰产生的虚警检测概率和漏检概率数学表达式,并研究了不同参数对系统BER性能的影响. 仿真结果表明,在多音干扰功率大于一定值时,多音干扰数量是造成系统BER性能下降的主要因素.

| Abstract: | With the characteristic of fast frequency hopping/M-ary frequency shift keying communication systems,mathematics expressions of the probability of false alarm and the probability of deletion(miss probability) are derived in Rician fading channels.The bit error rate(BER) performance with different parameters are researched and simulated.The results show that the bit error rate performance are main dependent on the number of multitone jamming(MTJ) in Rician fading channels when the power of MTJ is enough large. |
