Abstract

Abstract: A typical pattern division multiple access (PDMA) utilizes the cyclic prefix based orthogonal frequency division multiplexing (CP-OFDM) as the multicarrier modulator,and hence its capacity is reduced owing to cyclic prefix insertion. To address the issue, cyclic prefix free OFDM(CPF-OFDM) wireless transmission technologies is studied. Then a PDMA scheme based on CPF-OFDM is proposed and the main structure for its transceiver is designed. In addition,to evaluate the system performance, the system capacity and bit error rate are evaluated with different key parameters, such as overloading rates, channel conditions and signal-to-noise ratios. Simulation results show that the proposed CPF-OFDM PDMA are harvest a significant gain in terms of capacity compared with a conventional PDMA based on CP-OFDM.

Key words: cyclic prefix, pattern division multiple access, orthogonal frequency division multiplexing, capacity
