IMPLEMENTATION OF OFDM-IDMA USING RAYDON TRANSFORM

Author: PAYAL SAHU1, DEEPTI RAI2

Category: Engineering, Science and Mathematics

Abstract:

OFDM is a digital modulation scheme in which a wideband signal is split into a number of narrowband signals. Because the symbol duration of a narrowband signal will be larger than that of a wideband signal, the amount of time dispersion caused by multipath delay spread is reduced.

The proposed system consists of a novel FRAT (Finite Radon Transform) based model which enables the communication media to scrutiny the noise and also cater for Inter symbol interference also it has been shown that the said system showed good BER performance as compared to other systems, also as the result will show that the ISI reduction is more in our system also the zero padding pose to be a problem which could be rectified in the times to come.

Keywords: OFDM, OFDM-IDMA, frame interleave, fast Fourier transform, wavelet transform.
