英文摘要： This project will focus on the study of multi-pair two-way relaying wideband wireless networks. Based on real channel model and system parameters,in the case of wideband and interference, we design optimal pilot pattern and channel estimator, and seek how to fully exploit space, frequency, and multiuser resources, by wideband beamforming and space-frequency channel pairing tools, to design a high-efficiency space division multiple access and information exchanging scheme, to improve the sum-rate of information exchanging/transmission and the performance of detection, and to manage the serious interference among user pairs at relay station (RS) with a high efficiency. We plan to derive and analyse the outage probability, symbol error rate, spectrum efficiency, asymptotic degrees of freedom and capacity when we can obtain ideal or not ideal channel state information and the number of antennas at RS approaches middle or large-scale. Then, we develop a high-sum-rate and low-complexity cascading transmission scheme at RS to achieve a joint optimal optimization of system as the number of antennas at RS approaches large-scale.The project research will result in a large progress on application of multi-pair two/multi-way relaying to the future generation mobile communication, satellite communication, mobile ad-hoc network, and public safe network,thus,its study has very important theory value and wide application potential.
