It is now well known that employing channel adaptive signaling in wireless communication
systems can yield large improvements in almost any performance metric. Unfortunately …

Multiple transmit antennas in a downlink channel can provide tremendous capacity (ie,
multiplexing) gains, even when receivers have only single antennas. However, receiver and …

Novel low-density signature (LDS) structure is proposed for transmission and detection of
symbol-synchronous communication over memoryless Gaussian channel. Given N as the …

The fifth generation (5G) of wireless communication accompanied by the advancement of
mobile internet and the Internet of Things (IoT) will create stormy data traffic. The 5G …

The application of mathematical analysis to the study of wireless ad hoc networks has met
with limited success due to the complexity of mobility and traffic models, the dynamic …

Base station cooperation improves the sum-rates that can be achieved in cellular systems.
Conventional cooperation techniques require sharing large amounts of information over …

We present an optimized secure multi-antenna transmission approach based on artificial-
noise-aided beamforming, with limited feedback from a desired single-antenna receiver. To …

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 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 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 …
