Performance Analysis of OFDM System Using Non-conventional Transform and Non-conventional Mapping Schemes over Rayleigh Channel
Abstract: ABSTRACT High data rate wireless transmission is required to meet the rapidly increasing demands for mobile communications. Fast Fourier transform (FFT)-OFDM has drawn much attention due to its simple implementation and robustness against frequency-selective fading channels. Recently, the advantages of the discrete cosine transform (DCT)-based OFDM have come to the light. In this paper, performance of the conventional FFT-OFDM system is compared with non-conventional DCT-OFDM in terms of bit error …
