Paper Title - A New Technique For Vhdl Implementation Of Spectrum Sensing In Cognitive Radio

Spectrum sensing is one of the great challenges in cognitive radio because growing demands of bandwidth for wireless applications has put a lot of constraints on the available radio spectrum which is limited and precious. Energy detection is now a days quite popular sensing technique for cognitive radio because of its advantages. On the basis of energy detection, a number of techniques have been proposed in literature to detect white spaces for the primary user. Several papers show that the probability of detection increases significantly when signal to noise ratio increases. It is also observed that the detection probability decreases when the bandwidth factor increases. In present article, VHDL implementation of the energy detection method has been proposed by using a simulation tool Xilink. The added advantage over the previous literature available is that elimination of PN sequence generation results in decreased BER. Simulation results show the utility of work done. Keywords— Spectrum Sensing, Cognitive Radio, White Space, Energy Detection Techniques, Energy Detection.
