扩频通信中对强窄带干扰进行变换域预测后系统的误码率-Spread Spectrum Communication strong narrow-band interference in transform domain to predict system bit error rate after

这个代码是用来对数字通信系统中FFT变换进行仿真，将时域信号进行FFT变换可得到频谱图形-This code is used to simulate the FFT algorithm in digital communication systems, time-domain signal available spectrum graphics FFT

变换域通信TDCS通过信道估计在变换域设计信号波形，其次没有采用载波调制，而是用一个类似噪声的基函数进行信息调制。TDCS具有很强的抗干扰能力和较高的低截获特性。-Transform Domain Communication TDCS through the channel is estimated in the transform domain signal waveform, followed by no-carrier modulation, but with a noise-like b

仿真了在收发两端频谱环境不一致情况下变换域通信系统的误码率仿真(The BER of the transform domain communication system is simulated when the spectrum environment is not uniform)

仿真了变换域通信系统在自适应方法和遗传算法优化神经网络方法下的误码率(The BER of the transform domain communication system is simulated by adaptive method and genetic algorithm)
