基于频域复杂度分析的频谱感知算法
Spectrum sensing algorithm based on frequency domain Lempel-Ziv complexity analysis
摘要
Abstract
A spectrum sensing algorithm based on LZC analysis in spectral domain was proposed.CR users transform the received signal into spectral sequences.Then the sequences are analyzed by LZC method so as to distinguish noise from signal and decide the activity of PU.This algorithm promotes the detection probability under low SNR.Simulation result show that the proposed method resists to SNR uncertainty and improves the sensing performance in cognitive radio networks.关键词
