Antenna selection in Multiple-Input-Multiple-Output (MIMO) systems preserves diversity gain
while significantly reducing hardware complexity. However, imperfect Channel State …

Utilizing artificial noise (AN) is a good means to guarantee security against eavesdropping
in a multi-input multi-output system, where the AN is designed to lie in the null space of the …

In unitary precoded multi-antenna systems with delayed feedback, the quantized channel
state information (CSI) may become outdated before its actual use at the transmitter. In this …

Base station cooperation transmission, which is also known as coordinated multi-point
(CoMP) transmission, is a promising technique to improve system spectrum efficiency in …

For broadband wireless communication systems, Orthogonal Frequency Division
Multiplexing (OFDM) has been combined with Multi-Input Multi-Output (MIMO) techniques …

Reliable communication over delay-constrained multiple-input multiple-output (MIMO) block-
fading channels with discrete inputs and mismatched (imperfect) channel state information …

In this paper, we analyze the performance of an adaptive Multiple Input Multiple Output
(MIMO) system employing transmit antenna selection and rate adaptation based on channel …

In this paper, we analyze the fundamental power-delay tradeoff in point-to-point OFDM
systems under imperfect channel state information quality and nonideal circuit power. We …

In this paper, a SVD based multicell MU-MIMO uplink transmission and joint detection (JD)
scheme is presented. It can decompose the MU-MIMO system into SU-MIMO channel and …

As the number of devices connected to internet has increased, the demand for capacity in
cellular networks has increased as well. One attractive method to increase the capacity is to …
