LOS MIMO系统多相位跟踪与补偿
Multiple phases tracking and compensation for LOS MIMO systems
摘要
Abstract
Aiming at the multiple phase noises in distributed transmitter and receiver antennas of LOS MIMO systems,a tracking and compensation algorithm for multiple phases based on LMS criterion and linear equalization is proposed.The symbol error rate (SER) performance is analyzed by simulations under various oscillator configurations,phase noise bandwidth,modulation orders and step sizes.Then,compared with the existed algorithm based on phase-locked loop (PLL),the simulation results show that the SER performance of the LMS algorithm is superior to the PLL algorithm.The proposed LMS algorithm can reduce the SER of LOS MIMO systems more efficiently,thus is more practicable than the PLL algorithm.关键词
