Performance evaluation of CoMP methods under RF calibration errors

摘要

Coordinated multipoint (CoMP) transmission-reception systems promise an enhanced cell-edge user downlink throughput, specially in time division duplexing (TDD) systems. Radio frequency (RF) calibration is necessary for proper CoMP operation. In this paper, we study the performance of different CoMP schemes and different precoders under RF mismatch calibration errors. Numerical results are provided which show the best CoMP mode candidates given different SNR and calibration error levels.
