Abstract :
Non-linear frequency domain equalization schemes which give better performance than linear frequency domain equalization schemes, have recently been proposed in the literature for single carrier (SC) systems. In this paper, we study performance of non-linear frequency domain equalization schemes, viz. decision feedback equalization (DFE) and iterative DFE, for DS-UWB systems. We compare bit error rate (BER) performance of various time domain and frequency domain equalization techniques and evaluate their computational complexity. We show that the frequency domain equalization techniques can offer better trade off between complexity and performance compared to the time domain equalization techniques for DS-UWB systems.
