Abstract

The use of cognitive radio technique for wireless transmission becomes a demand in the field of data communication. The spectrum sensing is an important part of cognitive radio. There are number of research work has been carried out in the field of the spectrum sensing for cognitive radio. In this paper we have presented the various methods of spectrum sensing along with pits and falls of methods. A comparative a nalysis on the basis of the performance parameters is also given in the paper. The probability of detection with respect to probability of false ala r m and SNR is key parameter for detection. Single sensor and multiple sensor based detection is also given i n the paper
