本文介绍了一种采用快速傅里叶变换（FFT）处理器和裁剪器的二进位频移键控快速跳频扩频系统的性能分析。基于fft的剪波接收机提供了一种在离散时域抑制部分频带干扰（PBJ）的方法。得到了误码概率的解析表达式，数值结果表明，基于fft的接收机的性能优于线性组合接收机，与clipper接收机的性能相当。
This paper presents the performance analysis of a binary frequency-shift keying fast frequency-hopping spread-spectrum (BFSK/FFH SS) system equipped with a fast Fourier transform (FFT) processor and a clipper. The FFT-based clipper receiver provides an alternative approach to suppress partial-band jamming (PBJ) in discrete-time domain. The analytical expression for the probability of bit error is obtained and numerical results show that the performance of FFT-based receiver is better than that of the linear-combining receiver and comparable to that of the clipper receiver.
