This is the generation code for direct spread spectrum using pseudo-random noises. it shows how to generate it and also is implemented bit error ratio and the checking of autocorrelation.

采用频域FFT变换实现对雷达回波信号的MTI处理，有效的提高信噪比，本程序是对这一过程的验证。(Using frequency domain FFT transform of radar echo signal processing on the MTI, effectively improve the SNR, the procedures for the process validation.)

— In ultra-wideband (UWB) indoor dense multi-path transmission environments, traditional coherent Rake receiver requires estimation of channel parameters. Moreover, in order to collect enough signal energy from dense multi-path components, the number of Rake fingers must be large enough. Consequently, the receiver structure is too complex to be implemented in practice.
