Demodulation for wireless ATM network using modified SOM network
Li Jiang, Qilian Liang, MICHAEL T. MANRY · 2004
We study the demodulation problem in time division multiple access (TDMA) wireless asynchronous transfer mode (ATM) networks, where Rician flat fading channels are considered. A linear interpolation with decision feedback combined with a modified version of the self-organizing-map (LIDF-SOM) demodulator is proposed for such a system. We obtain the training sequence by exploiting medium access control (MAC) and data link control (DLC) protocols such that a semi-blind adaptive demodulator is implemented. Simulation results show that LIDF-SOM obtains 0.4-1.0 dB gain over Rician fading channels as compared to LIDF alone.
