The spreading signal is a pseudo-noise code sequence that has a chip rate which is orders of magnitudes grater than the data rate of the message.
扩频信号是一个伪随机代码序列，此码片速率比消息数据速率高若干数量级。
But if above positive real condition is satisfied only within some frequency range, the convergence of FXLMS algorithm is dependent on the spreading of power spectral density of the reference signal.
若上述正实条件仅在某些频带上满足，则FXLMS算法的收敛将依赖于参考信号功率谱密度的分布。
Base_station USES finite number of space_time codes to spread, and small number of antennas to transmit and receive signal, thus TD_SCDMA mobile terminals can obtain maximal spreading gain.
用有限的空时码进行扩谱，并利用较少的发射天线和接收天线进行信号的发射与接收，从而在TD _ SCDMA移动接收端获得最大的扩谱增益。
