Multiple phases tracking and compensation for LOS MIMO systems
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 phaselocked 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.
