Abstract |
|
The key challenge of spectrum sensing is the detection of weak signals in noise with a very small probability of miss detection, which requires better understanding of very low SNR regimes. Using a Cognitive radio allows unlicensed users to access licensed frequency bands through dynamic spectrum access so as to reduce spectrum scarcity. The spectrum sensing problem has gained new aspects with cognitive radio and opportunistic spectrum access concepts, it is one of the most challenging issues in cognitive radio systems the paper explains sensing concept and its various forms. First cognitive radio standard called the Wireless Regional Area Network (WRAN). Physical and Medium Access Control (MAC) layer specifications are the main highlight of the standard. In the physical layer, the transmissions of IEEE802.22-based devices on target frequency bands are division multiple access (OFDMA).Multiple TV bands can be used simultaneously to enhance the system throughput by bonding techniques |
