Performance Comparison of Uplink Cognitive Cellular Network Under Rayleigh and Nakagami-M Fading Environments
In this paper, the authors consider a mobile cellular network where two types of users: Primary User (PU) and Cognitive User (CU) share the entire spectrum of the Base Station (BS). Opportunistic scheduling scheme of CU is widely used to alleviate interference between CU and PU users. Recent literature deals with such networks under Rayleigh fading environment. This paper is to determine the performance of such networks under Nakagami-m fading environment and to compare the results with the results for the Rayleigh fading model. The paper shows the comparison of average Bit Error Rate (BER) and mean channel capacity of target transmission rate taking outage probability as a parameter.
