摘要: We study the equalization problem in time division multiple access wireless asynchronous transfer mode (ATM) systems. Aiming at minimizing overhead associated with equalization, we propose a protocol-aided channel (PACE) approach for ATM. Specifically, medium control (MAC) and data link (DLC) protocols are exploited to provide known ATM cell headers receiver base station. A blind estimation-decision feedback equalizer (BCE-DFE) algorithm is developed uplink transmissions. There two advantages of BCE-DFE algorithm: elimination training symbols bursts removal estimation error propagation suffered by conventional block schemes. Simulation results show has robust performance transmissions over fast time-varying channels.
