摘要

本文对认知CDMA网络中联合接纳与功率控制(JAPC)算法的性能进行了仿真研究。在由主用户(PU)和副用户(SU)组成的CDMA网络上行场景下，对SU的性能进行了评估。研究了许多算法。在我们的模型中，除了路径损耗外，还假设了长期衰落以评估这些算法的性能。提出了一种低复杂度的最小信号强度去除算法(MSSRA)。在存在pu的情况下，所有这些算法的性能都在收益和阻塞概率方面进行了评估。

Performance of joint admission and power control algorithms in Cognitive-CDMA Network

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.
