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.)

针对MIMO-OFDM系统中期望最大化(EM)信道估计算法在高信噪比(SNR)下带来的误差地板(EF)现象,且OFDM符号的数据传输效率随发射天线数的增加而明显降低,提出一种改进的高效EM信道估计算法。该算法首先引入一种准确的等效信号模型并推导出一种修正的EM算法,改善了EM算法在高SNR下的性能 在多个OFDM间利用相位正交导频序列来提高数据传输效率,同时进行联合信道估计以提高估计性能。仿真实验验证了所提算法具有更高的信道估计性能和更高的数据传输效率。(For multiple-input multiple-output with orthogonal frequency division multiplexing(MIMO-OFDM) systems,the error floor(EF) phenomenon at high signal noise rate(SNR) was induced by the expectation maximum(EM) channel estimation algorithm.In addition,the data transmission efficiency was declined obviously with the increasing number of transmit antennas.According to these problems,an improved and efficient EM channel estimation algorithm was pro-posed.Firstly,an accurate and equivalent signal model was introduc...)

(Error-controlled coding techniques are used to detect and/or correct errors that occur in the message transmission in a digital communications system. Wireless personal channels used by mobile communications systems and storage systems for digital multimedia data all require the implementation of error control coding methods. Demonstrating the role of coding in communication and data storage system design, this text illustrates the correct use of codes and the selection of the right code parameters. Relevant decoding techniques and their implementation are discussed in detail. Providing communication systems engineers and students with guidance in the application of error-control coding, this book emphasizes the fundamental concepts of coding theory while minimising the use of mathematical tools.
