Abstract

For alleviating the fixed and high complexity, high peak to average power ratio (PAPR), and sensitivity to carrier frequency offset problems caused by the large size of Fast Fourier Transform (FFT) in general OFDMA systems, the time-division OFDMA (TD-OFDMA) systems, based on an innovative concept of the Layered FFT structure, was recently proposed. In this paper, the theoretical analysis is presented to compare the BER performance of OFDMA and TD-OFDMA systems in frequency selective fading channels. Two frequency domain equalization (FDE) techniques, i.e., the zero forcing (ZF) and minimum mean square error (MMSE) criteria, are considered. Theoretical analysis, verified by simulations, shows that the TD-OFDMA systems can achieve similar and even better performance than conventional OFDMA systems when a MMSE equalizer is applied.
