Power allocation of MIMO system with RF mismatch in TD-LTE power wireless private network by Bao FENG, Tao MA, Shilong CAI, Yang LI

“…With the development of smart distribution network,the power wireless private network using TD-LTE technology has gradually become a hot research topic.Among them,multiple-input multiple-output (MIMO) system is a key technology of TD-LTE power wireless private network.In TD-LTE,time-division duplex is often used to estimate channel information and perform appropriate power allocation to maximize the spectral efficiency of the communication system.However,due to the mismatch of radio frequency link,the complete uplink and downlink channels in the actual communication system can not achieve complete symmetry.The performance of MIMO system under radio frequency mismatch was analyzed and the suboptimal power allocation scheme was given.Combining with the approximate capacity expression,the spectral efficiency of the system under radio frequency mismatch and matching was analyzed.Simulation results show that compared with the optimal power allocation,the system capacity will suffer some loss due to the sub-optimal power allocation algorithm,but there is still some performance improvement compared with the equal power allocation algorithm,and does not require complicated calibration process.The realization of the operation proves the validity of the sub-optimal power allocation algorithm.…”
