Orthogonal frequency division multiplexing is a scheme of encoding digital information on numerous carrier frequencies. The orthogonality permits an proficient modulator and demodulator realization by means of FFT algorithm resting on receiver side, and inverse FFT resting on sender side. A substitute technique for orthogonal transmission and reception of data using Rajan Transform and Inverse Rajan Transform has been proposed in this paper. The performance of both systems are compared by measuring BER and from simulation results it is observed that the performance of the system gets improved by using Rajan Transform and Inverse Rajan Transform instead of IFFT and FFT.
