When channel state information (CSI) is available at the transmitter, the system throughput can be enhanced by adaptive transmissions and opportunistic multiuser scheduling. In this paper, we consider multi-input multi-output (MIMO) systems employing bit-interleaved coded orthogonal frequency division multiplexing (BIC-OFDM). We first propose a bit- loading algorithm based on the Levin-Campello algorithm...
In this paper, by using the moment generating function (MGF) method, we derived the exact symbol error rate (SER) of multiple-input multiple-output (MIMO) system with transmit-antenna selection in a full-correlated fading channel. There are three assumptions in this work. The first is that the channel state information (CSI) is available only at the receiver but not at the transmitter. The second...
This paper proposes a pilot-based channel state information (CSI) feedback in time-division duplex (TDD) / multi-input multi-output (MIMO) system, which enables the transmitter to perform transmit beamforming considering the receiver's interference. In the proposed method, the receiver sends reverse-link pilot signals spatially prefiltered by linear precoder dependent on the receiver's interference...
This paper considers theoretical link spectral efficiency limits of multi-antenna channels with composite Rayleigh multipath fading and log-normal shadowing. The relevant limits include epsiv-achievable and delay-limited link spectral efficiencies which are defined with respect to the availability of the channel state information at the transmitter and the receiver. The numerical results suggest that...
We investigate the diversity gain of MIMO systems with antenna selection in measured propagation channels for wireless personal area networks. We measure both the communication from an access point to a laptop, and between two handheld devices. Both the transmitter and receiver use antenna selection for diversity transmission and reception. We consider a closed-loop system where the transmitter has...
