请问现在均衡还有研究空间么？

That's the problem in almost every area of communications, not just for equalization.But I have to admit that equalization is no longer a fruitful field.
So a lot of researchers in signal processing transfer their focus to networks, or even bioinfomatics. Those are much hotter, and much easier to get funding.

我导师就是 本来做信号处理的 现在开始转网络了
但是现在似乎通信的各个方向都有饱和的趋势阿
毕竟通信不像计算机有无限多的应用领域
混饭吃不易啊

你说的是生物信息论吗？有科普的读物给大家看看吗？

目前有关均衡的文章每年都有很多。
