Feedback in a communications system can enable the transmitter to exploit channel conditions
and avoid interference. In the case of a multiple-input multiple-output channel, feedback …

Given a multiple-input multiple-output (MIMO) channel, feedback from the receiver can be
used to specify a transmit precoding matrix, which selectively activates the strongest channel …

We consider a single-user, point-to-point communication system with M transmit and N
receive antennas with independent flat Rayleigh fading between antenna pairs. The mutual …

We study the capacity of a single-user channel with multiple antennas and limited feedback.
The receiver has perfect channel knowledge, and can relay B bits, which specify a …

We study the performance of joint signature-receiver optimization for direct-sequence code-division
multiple access (DS-CDMA) with limited feedback. The receiver for a particular user …

Channel estimation is a critical component in orthogonal frequency division multiplexing (OFDM)
systems for ensuring reliable wireless communication. In this study, we propose a fast …

We examine the capacity of beamforming over a single-user, multiantenna link taking into
account the overhead due to channel estimation and limited feedback of channel state …

The Device-to-Device (D2D) communication underlaying cellular networks is considered in
this study. The D2D transmitter in the D2D mode can directly transmit messages to a receiver…

We investigate how the number of radio frequency (RF) chains and the training power for
channel estimation affect the sum-achievable rate in the massive MIMO downlink. With a …

We examine the capacity of beamforming over a multi-input/single-output block Rayleigh
fading channel with finite training for channel estimation and limited feedback. A fixed-length …
