认知无线电中发射端多波束形成算法及接收端低旁瓣波束形成算法
Multi-Beam Transmit Beamforming and Low-Sidelobe Receive Beamforming Algorithm in Cognitive Radio
摘要
Abstract
In CR networks ,a transmitting and receiving beamforming algorithm is proposed .In transmit‐ting beamforming ,a multi‐beam algorithm is proposed to send different signals to different secondary us‐ers .In receiving beamforming ,a low side‐lobe beamforming algorithm is presented .To avoid the inter‐ference when primary and secondary users share the same spectrum ,the problem of transmitting beam‐forming is transformed into the one that can be solved by CVX toolbox .In receive beamforming ,based on the method of array pattern optimization ,a low side‐lobe level receiving beamforming algorithm is proposed in primary base station to suppress the white noise and unexpected interference .Extensive nu‐merical results using simulated wireless channels in two dimensions are presented to verify the effective‐ness of the algorithm .关键词
