Based on the principle of digital orthogonal modulation, the generation question of wide-band signal is factually identical with how to generate base-band signal with high sampling in time domain.

在数字正交调制原理的基础上，宽带信号的产生问题实际上转换为如何得到高采样率下的时域基带信号。

Any Doppler drift in the signal would fall within this wide band anyway and will form part of the total signal.

信号的任何多普勒频移无论如何都不会移出这个频带，而且也肯定会是整个信号的一个组成部分。

The receive technology of Ultra-Wide Band (UWB) signal is one of the key technologies of high-speed receiver. Quadrature receiver is typical scheme in high- speed receiver.

超宽带信号接收技术是高码率接收系统的关键技术之一，正交接收机是实现超宽带信号接收的典型方案。
