用最大似然法检测数字通信中的信号

Maximum Likelihood Detection for Signals of Digital Communication

最大似然检测方法广泛应用于工程之中。本文从通信系统的角度介绍了似然比检测的原理,利用最大似然检测的原理,实现无线通信系统中的似然检测的方法。与目前已有的其他常规方法相比,最大似然检测明显提高了系统的检测性能。

The paper presents a general idea of maximum likelihood detection,in which likelihood ratio is essential.Approaches of handling the likelihood ratios are discussed in the paper.The likelihood ratio's applications in digital communication systems are discussed in details.Comparing with other methods,maximum likelihood detection markedly improves the detection performance of the system.
