This paper is concerned with the phase noise mitigation in millimeter wave (mmW) multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. We first develop a model for phase noise in the mmW MIMO-OFDM system with hybrid precoding. A pilot-assisted estimation and compensation (PEC) scheme is then proposed by jointly estimating the channel response and effective...
In our previous work, a hybrid transform coding (HTC) scheme was proposed for the compression and feedback of channel state information (CSI) in multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. In this paper, we investigate the performance of HTC in both the interfering broadcast channel (IBC) model and cellular network model. In IBC, the achievable...
This paper is concerned with the efficient compression and feedback of channel state information (CSI) in downlink multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. Inspired by video coding, we propose a novel CSI compression and feedback scheme, referred to as hybrid transform coding (HTC). HTC consists of two coding types, i.e., selective time-domain...
This paper is concerned with the efficient feedback of the channel state information (CSI) in multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. A hybrid transform coding (HTC) scheme is proposed by exploiting the frequency and time correlation of CSI. An upper bound for the overhead-distortion performance of HTC is derived. Numerical results show that,...
