基于回归特征分析的BPSK信号盲处理结果可信性评估
Credibility Evaluation for Blind Processing Results of BPSK Signals by Using Regression Features
摘要
Abstract
A credibility test method based on the features of the linear regression is proposed to evaluate the blind processing results of binary phase shift keying (BPSK) signals such as the modulation recogni‐tion and parameter estimation .The reference signals are first constructed depending on the certain identi‐fied modulation results .Two features ,the ordered regression factor and sign of the segments regression , are defined to test the credibility of the processing results by analyzing the differences of linear regression characteristics of the correlation series modulus between the original and the ascending order .Simulation results show that the proposed method can be used to effectively verify the credibility for blind processing results of BPSK signals both at low signal‐to‐noise ratio and the condition without a prior knowledge for signal parameters .关键词
