该算法是迄今为止我找到的最好的最完整的单载波频域均衡的原理。众所周知，时域均衡一直是接收机的瓶颈能估，频域均衡则要简单的多。频域均衡使用基于块传输的机制，类似于OFDM，并且是单载波的。接收机十分完整，包含载波同步、帧同步等，最重要的均衡处理。(This algorithm is the best and the most complete single carrier frequency domain equalization principle I have found so far. As we all know, time domain equalization is always the bottleneck of the receiver, and frequency domain equalization is much simpler. Frequency domain equalization is based on block transmission mechanism, which is similar to OFDM and is single carrier. The receiver is very complete, including carrier synchronization, frame synchronization, and so on, the most important equalization processing.)
