Abstract
Higher speed will cause more serious Doppler spread, meanwhile change the character of the wireless channel, which breaks suppose that the channel impulse respond (CIR) is a constant during a time slot. In order to overcome this problem, this paper proposed an algorithm which is RS-MAP-PSP (adaptive reduced state maximum a posteriori equalizer based on per-survivor processing) in conjunction with DFE (decision feedback equalizer) for the EDGE system with 8PSK modulation. To reduce the state of the equalizer, a pre-filter is followed by the MAP-PSP to reshape CIR to have approximately a minimum phase property. Our simulation results show that the proposed algorithm can improve the performance of the EDGE system, compared with general receiver algorithm especially for the high coding rate traffic and/or under the high speed environments.
