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.
