Statistical antenna selection for spatial multiplexing systems

Spatial multiplexing is a signaling strategy for achieving high spectral efficiencies in communication links that employ multiple transmit and multiple receive antennas. In such systems it will be desirable to use only a subset of the available transmit and/or receive antennas to reduce cost and complexity. In this paper we address the problem of optimal antenna subset selection in spatial mult...

Limited feedback precoding for spatial multiplexing systems

Spatial multiplexing multiple-input multiple-output (MIMO) wireless systems are of both theoretical and practical importance because they can achieve high spectral efficiencies by demultiplexing the incoming bit stream into multiple substreams. It has been shown that sending fewer substreams than the number of transmit antennas by linear precoding can provide improved error rate performance. Me...

Transmit Antenna Correlation in Spatial Multiplexing Systems

In this letter we present a transmit antenna correlation in spatial multiplexing systems with channel state information at the transmitter (CSIT) of a multiple-input multiple-output (MIMO) correlated channel. Indeed, high correlation degrades system capacity and performance. Most related work has thus far considered in the statistical channel model such as Kronecker model with an approximate To...

Power Allocation for Dual Transmit Antenna Spatial Multiplexing Systems

In this paper, power allocation schemes for dual transmit multiple receive antenna communications is proposed and analyzed. Minimum error rate power allocation for a number of equalization schemes are proposed, including zero-forcing (ZF), successive interference cancellation (SIC) and ordered SIC (OSIC). It is shown both analytically and by numerical simulations that the proposed schemes impro...

Diversity-Multiplexing Tradeoff in Multiple Antenna Systems with Quantized Feedback

In this paper, we derive lower bounds on optimal diversity-multiplexing tradeoff in multiple antenna channels when the transmitter has finite bits of channel state information. We show that for each multiplexing gain, the diversity order is higher than the case without feedback. Furthermore, as the number of feedback bits increases, the diversity-multiplexing tradeoff grows unboundedly to appro...
