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.
