Cognitive Radio Spectrum Sensing with OFDM: An Investigation

Md. Shahnawaz Shaikh, Pavan Kumar Khare


Wireless communication applications are exponen-tially enhancing their utilization in the various streams. This huge technological development requires wide frequency spec-trum availability with fast and secure wireless communication technology. In this approach bandwidth scarcity might creates an important obstacle in the progress of wireless communication applications. Cognitive Radio (CR) and Orthogonal Frequency Division Multiplexing (OFDM) are the two novel emerging tech-nologies, enhancing the capacity of wireless communication appli-cations. This paper explains, CR systems with their requirements of the physical layer are discussed. Orthogonal frequency division multiplexing (OFDM) technique also investigated as a premier candidate transmission technology for CR. The efficient and meaningful challenges are recognized while employing OFDM in CR systems
