Adaptive MIMO Antenna Selection
The performance of multiple-input multiple-output (MIMO) systems can be improved by employing a larger number of antennas than actually used and selecting the optimal subset based on the channel state information. Existing antenna selection algorithms assume perfect channel knowledge and optimize criteria such as Shannon capacity or various bounds on error rate. This paper examines MIMO antenna...
متن کاملProposal of Receive Antenna Selection Methods for MIMO-OFDM System
The combination of Multiple-Input Multiple-Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) technologies gives wireless communications systems the advantages of lower bit error rate (BER) and higher data rate in frequency-selective fading environments. However, the main drawbacks of MIMO systems are their high complexity and high cost. Therefore, antenna selection in MIMO sys...
متن کاملA Low Complexity Antenna Selection Algorithm for MIMO System
The performance of Multiple-input multiple-output (MIMO) system can be improved by employing a large number of antennas than actually used and selecting the optimal subset based on the channel state information at receiver. Antenna selection is used for increasing the channel capacity of MIMO systems and reducing the systems complexity and cost of RF chains. In this paper we propose an effectiv...
متن کاملPhase-shift-based antenna selection for MIMO channels
This paper addresses the antenna subset selection in multiple antenna systems with full diversity transmission, for both correlated and uncorrelated channels. To reduce the severe performance degradation of traditional selection/combining schemes, we prpose to embed phase-shift-only operations in the RF chains before selection. The resulting system shows a significant advantage in utilizing the...
متن کاملMaximum MIMO System Mutual Information with Antenna Selection and Interference
Maximum system mutual information is considered for a group of interfering users employing single user detection and antenna selection of multiple transmit and receive antennas for flat Rayleigh fading channels with independent fading coefficients for each path. In the case considered, the only feedback of channel state information to the transmitter is that required for antenna selection, but ...
