Abstract: In modern wireless communication, the radio spectrum is the most vital resource for a mobile operator. Most of the prime spectrums (licensed bands) are already allocated for license users for exclusive use. Few, unlicensed bands are left open for unlicensed users. Cognitive radios (CR) offer a solution to this spectrum scarcity problem and the demand for reliable high data rate transmission had been increased significantly these days, which leads the way to modulation techniques. The main objective of this paper is designing and analyzing of FSK Transceiver using Lab-VIEW and to measure the graphical representation of BER VsEb/No in the presence of Additive White Gaussian Noise (AWGN) of digital modulation schemes. FSK is chosen as modulation scheme for design of CR system is widely used for data transmission applications over band pass channels such as Cordless and paging systems, Telephone-line modems, Caller ID, Microcomputers, Audio cassettes, Radio control etc. FSK Transceiver is used to control the power for CR system. It is easy to implement and widely used for the wireless communication in VHF and UHF Frequency bands giving very good BER with high data rates.
