处理

With the progress of science and technology, pulse compression processing systems are developed to all-digital systems from analogue or digital-analogue ones. Digital pulse compression processing can be divided into pulse compression processing in time domain and pulse compression processing in frequency domain.

随着科学技术的进步，脉压处理系统从模拟式、数模结合式发展到全数字式，而数字脉压处理又可分为时域脉压处理和频域脉压处理。

Space-time processing technique combines time domain signal processing and spatial signal processing. It can utilize fully the space-time channel characteristic, repair limits of the time domain signal processing and spatial signal processing, and enhance the system capability, overlay area and transmission rate.

空时处理技术联合时域和空域信号处理技术，充分利用无线信道的空时结构特征，弥补了时域信号处理和空域信号处理二者的局限，能够提高无线通信系统的容量、覆盖范围和传输速率。
