The chernoff upper bound of the pairwise error probability(PEP) and the code design criteria are derived by means of the generalized likelihood-ratiotest(GLRT) decoding algorithm.
利用广义似然比检验（GLRT）解码算法，导出了成对符号错误概率（PEP）上限和码的设计准则。

The traditional signal detection theory and method using likelihoodratiotest has been used widely, but it has obvious drawbacks.
传统信号检测理论和方法主要采用似然比检测，已得到广泛的应用，但是存在明显的缺点。

It is shown that the asymptotic null distribution of the modified likelihoodratiotest proposed is derived and found to be relatively simple and easily applied.
