... within system constraints according to the complexity/performance tradeoff. 4. Simulations In this section, we present the BER performance of Q- OFDMA systems with different receivers, including linear ... Regarding to the work of DFE presented in this paper, our main contribution lies in extending the general DFE concept to the Q-OFDMA systems and testing its performance, instead of...
