Block phase estimation with decision feedback demodulator for satellite-based wireless ATM networks
Qilian Liang, Lingming Wang · 2006
In this paper, we propose a Block Phase Esti- mation with Decision Feedback (BPE-DF) based demodula- tion scheme for satellite-based time-division-multiple-access (TDMA) wireless asynchronous transfer mode (ATM) Net- works. Rician flat fading is assumed for the satellite chan- nel (no multipath). Because it's asynchronous between the transmission and receiver in wireless ATM networks, so demodulator is the most important design. Our simulation results show that our demodulator performs much better than the original block phase estimation demodulator in terms of uncoded bit error rate (BER) with a gain of 2-3dB.
