多接收天线下能量感知的性能研究
Research on Energy Detection with Multiple Receiving Antennas
摘要
Abstract
Energy detection with multiple antennas is studied in this paper. Energy detection with multiple antennas is able to achieve reliable detection in wireless multi-path fading channels. This method does not need extra communication bandwidth compared with multi-users cooperative spectrum sensing. Two energy detection multiple antennas methods,decision fusion and data fusion,are introduced. For multiple antennas with single energy detector,three data fusion rules are analyzed including AND rule,OR rule and K/ N rule. For multiple antennas with multiple energy detectors,maximum ratio processing and selection ratio processing are presented. The performance of multiple antennas with decision fusion and data fusion are analyzed and compared through simulation results.关键词
