Within digital communications, information is expressed inside in the form of bits. The term symbol refers to a collection, in a variety of sizes, of bits. At this time, Source data is taken from 8-bit grayscale bitmap image file and the preferred image data is rehabilitated into symbol size by means of D-PSK, and renovate by taking the Inverse Fast Fourier Transform (IFFT). Converted data will then be separated into multiple frames by the OFDM transmitter. Previous to the outlet of the transmitter, the modulated frames of time signal be cascaded together along with frame guards inserted in between as well as a pair of identical headers added to the beginning and end of the data stream.
