Executive Summary

A new multiple access scheme using Multi-Symbol Encapsulated Orthogonal Frequency Division Multiplexing (MSE-OFDM) is proposed. This is basically a Time Division Multiple Access (TDMA) technique utilizing the MSE-OFDM. The Bit Error Rate (BER) performance of the TDMA system using conventional OFDM is slightly better than that of the proposed system. This weakness is compensated as the proposed technique exhibits an improvement in bandwidth efficiency compared to the TDMA using conventional OFDM. In the recent years, Orthogonal Frequency Division Multiplexing (OFDM), a digital multicarrier modulation technique has found its application in many wideband wireless systems like Digital Audio Broadcasting (DAB), Digital Video Broadcasting (DVB) and High-speed Digital Subscriber Line (HDSL).
