This ML detector is based on an iterative least squares with projection (ILSP) algorithm exploiting both finite alphabet properties of the transmitted signal and its cyclic prefixed structure in order to approach ML detection in a cheap way. Since the initial channel estimate is crucial for the convergence of the ILSP algorithm, we propose a computationally cheap stochastic method for computing an initial channel estimate using a variant of cyclic prefix only (CP-Only): the known symbol padding only (KSP-Only) technique. The resulting channel model is sufficiently accurate to be used as a starting point for the iterations. The final result is a computationally affordable direct symbol estimation method that yields promising results in terms of bit error rate (BER).","PeriodicalId":336991,"journal":{"name":"2002 International Zurich Seminar on Broadband Communications Access - Transmission - Networking (Cat.

Because the subtraction of an interfering signal based on an incorrect bit decision quadruples the interference power for that signal, the relatively high decision bit error rate (BER) may lead to a poor cancellation or even a higher BER at the following stages. The RLSTT is a robust approach, which takes into account the fact that the tentative decision at the earlier stages is less reliable than the following stages and lets the earlier cancellation be more reliable. Theoretical analysis demonstrates that a better transmission performance can be achieved by using the RLSTT at the initial stage of PIC.","PeriodicalId":336991,"journal":{"name":"2002 International Zurich Seminar on Broadband Communications Access - Transmission - Networking (Cat.

Previously introduced linear equalization is augmented by three decision feedback filters to improve performance in presence of narrow-band interference (NBI), and to enable exploitation of implicit diversity of multipath fading channels. Adaptation properties of per-bin DFE equalization are analyzed by computer simulation. The bit error rate performance comparison between conventional OFDM and the OQAM-based multi-carrier systems is provided, and the potential advantage of using spectrally well shaped orthogonal subchannels in advanced wireless applications is pointed out.","PeriodicalId":336991,"journal":{"name":"2002 International Zurich Seminar on Broadband Communications Access - Transmission - Networking (Cat.
