IMPROVING THE PERFORMANCE AND REDUCING THE POWER CONSUMPTION OF PORTABLE HANDSETS IN TDMA MOBILE SYSTEMS BY CONDITIONAL EQUALIZATION

摘要

In TDMA systems, the autonomy of portable handsets is a major constrain. We propose a new method, condi- tional equalization, which minimises the power consumption due to equalization. The performance of our method is theoretically analysed for 2-path Rayleigh fading channels and simulated for the COST 207 models. Conditional equalization enables the saving of at least 30/100 of equalizations in urban environments with a loss in the SNR performance of less than 0.1 dB, and leads to a equalizations in rural area environment.
