The rollout of IEEE 802.16e for high speed mobile communications poses challenges to the design of equalizers for a time-varying multipath fading channel. This thesis investigates the effects of Doppler shift induced phase error in a wireless environment. It presents the performance of QPSK and MQAM waveforms with Doppler in a Rayleigh channel condition. It investigates the performance of ideal coherent modulation and pilot symbol-aided modulation in a Rayleigh channel with Doppler phase errors. The degradation in performance of pilot symbol-aided demodulation as compared to ideal coherent demodulation is presented. The study concludes with results of simulations of QPSK and MQAM waveforms in a Rayleigh Channel with Doppler pha...
