Abstract

We study the demodulation problems for enhanced general packet radio services (EGPRS) wireless systems, where Rician flat fading channels are considered. A linear interpolation with decision feedback combined with a modified self-organizing-map (LIDF-MSOM) demodulator is implemented for such systems. Simulation results show that the performance of the proposed demodulator is much better than that of LIDF alone.
