Cognitive Radio (CR) which aims to improve the spectrum utilization by accessing opportunistically the spectrum originally licensed to a primary system is a promising concept. OFDM is regarded as a potential technology for CR systems and dynamic resource allocation is an important task in such systems. This paper focuses on the sub carrier and power allocation algorithms which are to maximize secondary users' transmitted data rate while adjusting the interference introduced to the PU band below… CONTINUE READING
