摘要：We know that the radio electromagnetic spectrum is a natural resource and efficient usage of the inadequate natural resource is one of the greatest challenges of todays wireless communication system just like petrol, coal and water. The efficient use of the available licensed spectrum is becoming more and more critical with increasing demand and usage of spectrum, so this is an urgent need and requirement for the rapidly increasing number of wireless users and also for the conversion of voice oriented applications to multimedia applications. With efficient spectrum use, there are some parameters which also play an important role in the efficiency and performance of a system. One of them is Bit Error Rate (BER), the analysis i.e. optimization (minimization) of BER get better results. The aim of this study is to analysis BER theoretically as well as practically and shows the comparisons between them. In this paper, we analysis BER for better efficiency, high performance and maximum throughput in cognitive radio system based on Genetic Algorithm (GA).
