Tradeoff Analysis of Bit-Error-Rate (BER) in Cognitive Radio Based on Genetic Algorithm

The authors 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 today's 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.
