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。
Periodic training sequence is essential for the conventional adaptive equalizers to combat the isi , but it wastes plenty of bandwidth 采用传统的自适应均衡技术抑制码间干扰,需要重复发送训练序列,占用大量本不富裕的带宽。
Otherwise , this paper introduces the concept of the principle signal in the same channel transferred bidirectional and the phasic equalizer 并对这些器件的测试结果进行了讨论。讲述了同频信号双向传输原理及相移均衡器的简单概念。
The conventional equalizer resort to a training sequence in order to overcome inter - symbol interference . but this method would influence communication efficiency 传统均衡器克服isi的方法是发送训练序列,但是这会影响通信的效率。
Blind equalization techniques rely on solely the received channel output signal to adjust the equalizer weights without a known training sequence available 盲均衡就是不借助于训练序列而仅仅利用接收序列就实现均衡的一种新兴的均衡技术。
