Sudipta Ghosh, Chandika Mohan Babu . Conjectural Contriving of Orthogonal Frequency Division Multiplexing (OFDM) Transreceiver with the Aid of Phase Shift Keying (PSK) and a 256 bit Grayscale Image.

Orthogonal Frequency Division Multiplexing (OFDM) is one of the latest modulation schemes that is being used for high speed data transmission. OFDM is basically based on the principle of orthogonality, wherein the sub carriers are kept orthogonal. In order to decide the number of symbols per carrier we can use QAM and PSK. In this work of ours we have used PSK, specifically BPSK (i. e. 2 symbols per carrier). The basic purpose of this paper is to provide a MATLAB simulation of the basic processing involved in the generation and reception of an OFDM signal using a 256 bit gray scale image in a physical channel and to provide a description of each of the steps involved. In this paper we have two fields i. e. image processing and communication.
