Design and implementation of OFDM transceiver system using M-PSK encoding techniques

Multi-carrier or orthogonal frequency division multiplexing (OFDM) has become the chosen modulation technique for wireless communications because it provides a high data rate wireless transmission. Some examples of applications using OFDM include ETSI BRAN in Europe, IEEE802.11 in United States, and ARIB MMAC in Japan. Therefore, many research centers in the world have specialized teams working in the optimization of OFDM for countless applications. This paper is to demonstrate the concept and feasibility of an OFDM system, and investigate how its performance is changed by varying some of its major parameters by using a MATLAB program to simulate an OFDM system. From the process of this development, the mechanism of an OFDM system can be studied; and with a completed MATLAB program, the characteristics of an OFDM system can be explored.
