Abstract

With the rapid growth of wireless communication, Cognitive radio (CR) is a form of wireless communication in which a transceiver can intelligently detect which communication channels are in use and which are left open, and instantly move into vacant channels while avoiding occupied ones. This most effective use of available radio-frequency (RF) spectrum while minimizing interference to other users. The main objective of this paper is to comparative performance analysis M-Frequency Shift Keying (FSK) and MPhase Shift Keying (PSK) transceiver for CR applications using LabVIEW (Laboratory Virtual Instrumentation Engineering Workbench) This paper describes the fundamental concept for the design and implementation of a CR-based transceiver simulation model under FSK/PSK, Schemes, and to measure the Bit Error Rate (BER) in the presence of Additive White Gaussian Noise (AWGN) channel and analyses the performance of different types of codes. In this paper we have compare that how FSK gives very good BER providing high data rate and used to control the power for CR system than PSK. The BER curves for MFSK and MPSK obtained after simulation are compared with theoretical curves.
