Orthogonal frequency division multiplexing is a type of multicarrier modulation technique which is used in wireless communication. OFDM can be used in various wireless and wired application such Digital audio broadcasting, digital video broadcasting & wireless LAN. The Performance of OFDM system depends on various parameters such as using different transform, different modulation and by putting various channel coding. In this paper OFDM system is modeled by using different transform (DWT/FFT),

The performance parameter is calculated as Bit error rate (BER) for various transform/modulation/channel coding based OFDM systems. MATLAB Simulink tool is used to calculate the bit error rate (BER). Dr. M. K Soni did his B.Sc (Engg.) in 1972 and M.Sc (Engg.) in 1975 from REC Kurukshetra (Now NIT Kurukshetra) and thereafter completed his Ph.D from REC Kurukshetra (in collaboration with IIT Delhi) in 1988. He has a total 40 years of rich experience into Academics. His area of interest is microprocessor based control systems and digital system design. He has more than 100 research papers in the International and National Journals to his credit. Presently he is Executive
