Enhancement Of Secondary Link Capacity In Spectrum Sharing

Abstract:-In the previous investigations of secondary users capacity in spectrum-sharing environments have determined the secondary link capacity based on the interference power threshold set at the primary receiver. In contrast to these previous works, we analyze the secondary link capacity which is determined by the ratio of the distance between the secondary transmitter and primary receiver to the distance between the secondary receiver and secondary transmitter. The secondary user capacity is enhanced by this distance-ratio, for this the secondary transmitter has N antennas and a simple antenna selection process which is used to achieve better capacity. The numerical results obtained shows; improved capacity of the secondary link.
