Comparison Between Energy Detection and Cyclostationary Detection for Transmitter Section of Cognitive Radio
The available electromagnetic radio spectrum is in scarcity and is getting used day to day. On the
other hand it has been also found that the used spectrum is not utilized because of its static allocation which is
the traditional approach of spectrum management and is not flexible to operate in a specific frequency slot. And
most of the useful radio spectrum already used, it is difficult to find free bands to either deploy new services or
to improve existing ones Cognitive radio is viewed as a new approach for improving the utilization of a natural
resource: the radio electromagnetic spectrum. The paper compares various advantages and disadvantages of
Energy detection method and Cyclostationary detection method in cognitive radio. This comparison will help in
selecting an opportunistic method for spectrum sensing in cognitive radio.
