Orthogonal Frequency Division Multiplexing (OFDM) is a promising technique for high data rate wireless communications because it can combat inter-symbol interference caused by the dispersive fading of wireless channels. A FDM channel is like water flow out of a faucet, in contrast the OFDM signal is like a shower. In a faucet all water comes in one big stream and cannot be subdivided. OFDM shower is made up of a lot of little streams. The demand for high speed mobile wireless communications is rapidly growing. OFDM technology promises to be a key technique for achieving the high data rate capacity and spectral efficiency requirements for wireless communications of the near future which was a source of motivation for this project. Here in this paper, we simulate a cyclic prefix OFDM system with Binary Phase Shift Keying Modulation on each subcarrier. CP-OFDM system includes a repetition code and interleaving across subcarriers as well as a Rayleigh fading channel model with exponentially decaying power profile.
