Comparative Study of Energy Detection and Matched Filter Based Spectrum Sensing Techniques

The inefficient utilization of the radio spectrum leads to the invention of new techniques that help those users with no access or license to use the spectrum, whenever spectrum hole or free space is available. Cognitive radio is such a technology which finds the existence of a licensed user in the radio spectrum using dynamic spectrum access techniques. This paper discusses the comparison of Energy Detection and Matched Filter based spectrum sensing techniques in Matlab and Verilog. Implementation and analysis of Energy Detection and Matched Filter detection techniques using Verilog has also been performed and the results have been presented.
