In this paper, we apply a recently proposed low complexity iterative channel equalization technique, called the iterative decision feedback equalizer (IDFE) to a coded system using 8PSK modulation. In this system, the structure of the DFE has been modified to incorporate soft a priori information from previous iterations of the channel decoder in detection of the corrupted signal. As a result, in this algorithm complexity is only a linear function of channel memory length. Simulation results show that this technique, using a convolutional code with constraint length K=3 and interleaver size N=3000 over a known time invariant ISI channel achieves a remarkable gain of about 5 dB compared to the conventional DFE. Complexity evaluation also shows that the iterative DFE has advantages in terms of complexity compared to other types of turbo equalization techniques and is an appropriate candidate for EDGE (Enhanced Data rates for GSM Evolution) systems.","PeriodicalId":318292,"journal":{"name":"12th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications.

A promising measure to enable high downlink data rates consists in improving the carrier-to-interference ratios at the mobile receivers by the utilization or adaptive mufti-element transmit antennas. However, for the efficient operation of such antennas information about the downlink radio channels is required at the base stations. In the case of the 3G partial standard time division(TD)-CDMA designated for the time division duplexing (TDD) radio frequency bands, such information-thanks to the reciprocity theorem-is readily available from the uplink channel estimators. However, the 3G partial standard W(wideband)-CDMA designated for the frequency division duplexing (FDD) radio frequency bands suffers from the inherent disadvantage that, due to the frequency difference between uplink and downlink, the results of the uplink channel estimation cannot be directly used as the channel information required for adjusting the multi-element transmit antennas. Nevertheless, as long as the frequency difference between uplink and downlink is not too large, approaches to an at least sub-optimum adjustment of the downlink transmit antennas based on uplink channel estimates exist. In the paper such approaches are presented and evaluated by simulations.","PeriodicalId":318292,"journal":{"name":"12th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications.
