Alamouti空频码协作通信中的多载波频偏补偿
Multiple carrier frequency offsets compensation in Alamouti space-frequency block code cooperative communications system
摘要
Abstract
In cooperative communication systems,Multiple Carrier Fequency Offsets(MCFO) appear due to the different accuracy of the nodes' oscillators and Doppler spreads, which drastically degrades the performance of Space-Frequency Block Coded(SFBC) cooperative systems.The best amount of frequency shift is analysed, and an MCFO compensation algorithm is proposed including frequency shift and interference reconstruct. From the simulations, the proposed compensation algorithm achieves good BER performance with a large range of MCFO.关键词
