Abstract:
Due to the increasing demand on wireless communications the idea of cognitive radio is of utmost interest. The TV white space may become the first commercial application of cognitive radio resulting from its advantageous propagation properties. It allows the usage of secondary communication systems at non-occupied frequency bands. Within this manuscript, a prototyping platform for cognitive radio applications is presented. Its underlying architecture is based on a combination of DSP and FPGA and relies on the software-defined radio paradigm. Spectrum sensing algorithms are introduced for the three predominant Chinese TV standards DTMB, CMMB and PAL-D/K. Finally, the algorithms’ performance is shown in a comparison to simulation results. The focus of this manuscript is on a TV white space prototyping platform and the validation of spectrum sensing algorithms for the Chinese TV standards DTMB, CMMB and PAL-D/K.
