在这份报纸,我们分析快频率跳跃的位错误比率(BER )(FFH ) 在高活动性的无线隧道的有二进制阶段移动调音的系统(BPSK ) 。由考虑部分乐队噪音作为 Gaussian 噪音堵塞和隧道评价错误,最大比率的联合(MRC ) 并且(EGC ) 相等获得的联合策划被考虑,并且为 MRC 和 EGC 计划的准确分析 BER 表情被获得。特别,为 MRC 计划的靠近形式的 BER 表情也在高 signal-to-noise 比率区域被介绍。分析并且模拟结果表明那, FFH/BPSK 计划面对隧道评价错误受不了表演降级。堵塞因素的最糟的盒子被显示与到堵塞比率的信号相反地成正比。与跳跃计划和隧道评价策划的适当地设计的频率,表演改进也作为与传统的 noncoherent FFH/BFSK 系统相比被观察。
In this paper, we analyze the bit error ratio (BER) of fast frequency hopping (FFH) system with binary phase shift keying (BPSK) in high-mobility wireless channels. By taking into account partial band noise jam- ming and channel estimation errors as Gaussian noise, both of maximal-ratio combining (MRC) and equal-gain com- bining (EGC) schemes are considered, and exact analytical BER expressions for MRC and EGC schemes are obtained. Especially, a closed-form BER expression for the MRC scheme is also presented in high signal-to-noise ratio region. Analytical and simulation results demonstrate that, the FFH/BPSK schemes suffer from performance degra- dation in the presence of channel estimation errors. The worst case jamming factor is shown to be inversely pro- portional to the signal to jamming ratio. With properly designed frequency hopping schemes and channel estima- tion schemes, the performance improvement is also observed as compared with the traditional noncoherent FFH/BFSK system.
