Contriving of Orthogonal Frequency Division Multiplexing (OFDM) Transmitter with the Aid of Phase Shift Keying (PSK) and a 256 bit Grayscale Image

Orthogonal frequency division multiplexing (OFDM) is a special case of multicarrier transmission, where a single data stream is transmitted over a number of lower rate subcarriers. Orthogonal frequency division multiplexing (OFDM) has been chosen as modulation technique for different application wireless communications. OFDM can provide large data rates with sufficient robustness to radio channel impairments. The purpose of this paper is to provide a MATLAB simulation of the basic processing involved in the generation and reception of an OFDM signal in a physical channel and to provide a description of each of the steps involved. For this purpose, we shall use a 256 bit gray scale image as the input/data to be transmitted.
