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。
Because of the limits of feedback devices, high speed pseudo noise code generation cannot depend simply on the improvement of clock rate.
由于反馈器件的限制，高速伪码不能采用单独依赖提高时钟频率的方法。
