摘要
Abstract
Recently,Relay has become a booming and promising wireless communication technology,which can improve the information transmission quality and enlarge the service coverage area. Meanwhile,effective relay channel estimation makes up a foundation of other technologies for improving communication invironment,such as relay beamforming and relay selection. Focusing on the phase response in relay channel estimation,the model of phase noise in arbitrary SNR was build up. In order to decrease the amount of estimator calculation,the complicated formula of original noise model is approximated by the relatively simple Gaussian counterpart to get relatively succinct result. According on the different simplified form,several phase estimation algorithms are given. The CRLB(Cramer-Rao Lower Bound)is also derived with the purpose of comparing the performance of the algorithms. The conclusion correctness was verified by computer numerical simulation.关键词
