Abstract

The cognitive node which are far away from primary user (PU) which may not be able to detect the Primary User due to severe fading in the channel. To improve the efficiency of spectral sensing channel, we propose here a cooperative communication method this is based on cognitive relaying. Cognitive relay, which node that sense the activity of primary user and forward received data to the cognitive radio (CR) which is far away from primary user. In this condition the probability of detection can be increases, which in turn reduces the bit error rate. Using this number of a relay nodes can reduce the sensing time and increases the throughput of the system.
