Radio-Spectrum-Management-in-Cognitive-Radio.rar - Today’s wireless networks are characterized by fixed spectrum assignment policy. The limited available spectrum and the inefficiency in the spectrum usage necessitate a new communication paradigm to exploit the existing wireless spectrum opportunistically. Cognitive radio is a paradigm for wireless communication in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. It can capture best available spectrum to meet user communication requirements (spectrum management).,2016-04-24 18:47:00,下载3次
