Abstract

In this paper, a simulation study has been carried out to evaluate performance of joint admission and power control (JAPC) algorithms in Cognitive - CDMA Networks. Performance has been evaluated for SU in an uplink scenario of CDMA network consisting primary user (PU) and secondary user (SU). A numbers of algorithms have been investigated. Long term fading has been assumed in addition to path loss in our model for evaluating performance of those algorithms. We propose a minimal signal strength removal algorithm (MSSRA) which is a low complexity algorithm. Performance of all these algorithms has been evaluated in terms of revenue and Blocking Probability in presence of PUs.
