摘　　要：针对QPSK与BPSK通信体制下的信号相干检测错误概率的计算公式和相应的曲线往往互不相同,容易使人困惑的问题,为了达到正本清源的理解和应用的目的,对各种通信文献中涉及到的二者公式和相应曲线进行了汇总,结合基本原理和工程应用实践,对其本质进行了理论阐述,对差异之处进行了对比辨析,指出了二者的区别及其内在统一性,并作了工程应用小结。In allusion to difference between signal coherent detective error probability formulasin QPSK and BASP com- munication system and their corresponding curves, all kinds of formulas and their corresponding curves are summarized to a- chieve clear understanding and correct application. Combined with its rationale and engineering applications, the essences are academically expatiated, and the differences are compared to point out the discrepancy and inherent unification, and engineer- ing application summary is made.

关 键 词：四相相移键控 二相相移键控 相干检测 误码率
