Chapter 5 presents a novel approach to implement the sample rate variable pre - equalizer in the modulator 第四章分析了调制器末端用于采样转换的内插器。
Pre - equalizer is an option in the design of modulator , but it is always used in order to improve the quality of the if - signal 内插在调制器中的应用为方案良好的适应性提供了保证。第五章给出了变带宽预均衡的实现方案。
Sample rate variable is a must for the pre - equalizer in this scheme . analysis shows that the implementation of such pre - equalizer can be very simple and effective 变带宽预均衡是变符号串传输必然要解决的问题,本章在分析的基础上给出了简单的实现方法,并且通过实践证明有效。
