Co-Channel Interference Cancellation Algorithm Based on Maximum Entropy Method
Zhu Zhong-liang · Journal of Information Engineering University · 2007
To cancel co-channel interference in the digital communication,a single channel blind signal extraction algorithm is presented in this paper.Different from the existing blind signal extraction(BSE) models,the digital signals oversampling character is used in the model of this paper.At the same time,carrier frequency and the channel noise are taken into account.Jointed the constant module(CM) character of digital modulated signal,the CM generalized kurtosis algorithm is deduced.The results of experiments testify the validity and the stability.
