Efficient Channel Estimation for mmWave MIMO With Transceiver Hardware Impairments.
IEEE Transactions on Vehicular Technology(2019)
摘要
Transceiver hardware impairments (e.g., phase noise, high power amplifier nonlinearities, in-phase/quadrature-phase imbalance, and quantization errors) degrade the performance of channel estimation in millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems. Although compensation methods can be exploited to mitigate the impact of hardware impairments, there always remains residual im...
