基于霍夫变换的QPSK信号盲处理结果可信性评估
Reliability Test for Blind Processing Results of QPSK Signals Using Hough Transformation
摘要
Abstract
In order to assess the reliability of the QPSK signal processing results, an algorithm based on Hough transform is proposed. In the absence of a priori knowledge of the signal,by constructing an auxiliary signal based on the modulation and the corresponding parameter estimation results, the correlation sum between the original observed signal and the auxiliary signal is obtained. Based on the characteristics of the correlation modulus curve, the reliability test of blind signal processing is transformed to a test of whether the cluster number of the peaks of the Hough transformation is 1. The computer simulation results show that the average correct verification rate of the proposed algorithm is greater than 93% when the SNR is greater than -2 dB.关键词
