英文摘要： This topic is committed to improve the quality of channel parameters estimation and symbol detection with multi-receivers. Based on existing research, the joint processing of multiple parameters and multiple signals is applied, and the theory and methods research of multi-antenna signals reception under fading channels will be achieved. Our studies are concentrated on three aspects. The first research direction is to estimate the channel parameters of multi-receivers, joint channel identification and joint estimation based on combined reference will be studied. Second, a new scheme is proposed to achieve the parameter estimation and symbol detection jointly under time selective fading channels. The third research direction is joint equalization and diversity structures under frequency selective fading channels. The joint processing of equalization, timing recovery and symbol detection will be applied. The goal of this project is to improve the quality of reception and processing with multi-receivers, and the theoretical and technical supports will be provided for practical applications.
