Title : | Capacity Enhancement of Secondary Links through Spatial Diversity in Spectrum Sharing |
Authors : | Hano Wang, Jemin Lee, Sungtae Kim and Daesik Hong |
Journal : | IEEE Transactions on Wireless Communications |
Abstract : | Previous investigations on capacity of secondary users in spectrum-sharing environments have determined the capacity of a secondary link based on the interference power threshold set at the primary receiver. In contrast to these previous works, we show that the capacity of a secondary link is determined based on a geographical relationship expressed as the ratio of the distance between the primary receiver and secondary transmitter to the distance between the secondary transmitter and receiver. Proceeding from that and in an effort, to enhance the capacity of the secondary user, which is limited by this distance-ratio, we adopt a secondary transmitter with M antennas. Furthermore, we analyze the capacity achieved using a simple antenna selection process. |
