Abstract:-The essential problem of Spectrum Sensing Cognitive Radio is in designing high
quality spectrum sensing devices and algorithms for exchanging spectrum sensing data between
nodes. Applications of Spectrum Sensing Cognitive Radio include emergency networks and WLAN
higher throughput and transmission distance extensions. Engineers are now working to bring that
kind of flexible operating intelligence to future radios, cell phones and other wireless
communications devices. During the coming decade, cognitive radio technology should enable
nearly any wireless system to locate and link to any locally available unused radio spectrum to
best serve the consumer. It is proposed to investigate and develop cognitive radio algorithms to
enable co-existence between IEEE 802.11b and 802.16a networks in the same unlicensed band. In
particular, a system model would be developed in which the two wireless systems share radio
resources in frequency, space and time, and coordination methods will be used to reduce the
mutual interference and improve link throughput. The cognitive radio schemes will utilize the
available degrees of freedom in frequency, power and time, and react to observations in these
dimensions to avoid interference.
