  1. 1. Implementation and Analysis of Spectrum Sensing Algorithms for SIMO Links

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Techin Eamrurksiri; [2013]
    Keywords : cognitive radio; USRP; OFDM; Spectrum sensing; GLRT; SDR;

    Abstract : Cognitive radio is an autonomous transceiver that is continuously sensing theongoing communication in its environment, it then starts the communication whenever it is appropriate. Therefore, cognitive radio helps improving the spectrum utilization of the overall communication system. READ MORE
