Adaptive Bandwidth Allocation In Cognitive Radio

Abstract

Cognitive radio (CR) is a great advancement in the field of radio communications which also paves way for 4G wireless network. It is simply a combination of a transmitter a receiver and a spectrum sensor. The suitable requirements for establishing dynamic bandwidth allocation involves the knowledge about the network, type of modulation, SNR, noise floor, type of channel and also a suitable algorithm. It is essential to identify the performance of the network under various combinations. Here channel allocation must be made such as there is no interference to the primary users due to transmission by the CR's.
