Many wireless networks are rapidly become part of our daily life. However, range and data rate in wireless devices are limited. One method is to use Multiple-Input Multiple-Output (MIMO) communication system to overcome these limitations. The multiple antennas allow MIMO systems to perform diversity coding (space-time coding), and spatial multiplexing. Beamforming consists of transmitting the same...
We present a link adaptation strategy for multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) based wireless communications. Our objective is to choose the optimal mode that will maximize energy efficiency or data throughput subject to a given quality of service (QoS) constraint. We formulate the link adaptation problem as a convex optimization problem and expand...
In this paper, we construct antenna selection for spatial multiplexing in MIMO system; First, we present the channel model, then analyze of SER for spatial multiplexing with ZF receiver.The contribution of the paper is that accounting of the ZF receiver is reduced. Simulation results show that antenna selection could improve the performance of system.
