摘要
Abstract
The spread-spectrum waveform and information sequence blind estimation of DS-SS signals are studied in this paper. A new method of disintegrating the spread-spectrum waveform and information sequence blind estimation algorithum based on double PN periods is presented. The algorithm can accomplish the estimation of both spread-spectrum waveform and information sequence simultaneously under the low noise condition. Its computated quantity is small. Compared to traditional methods, this algorithm avoids the problem of phase ambiguity when the whole PN sequences are reconstructed by using the two parts of spread-spectrum waveforms. It can improve the validity of blind estimation. The simulation results verify the validity of this algorithm.关键词
