In this paper, we propose a robust transceiver design for the K-pair quasi-static MIMO interference channel. Each transmitter is equipped with M antennas, each receiver is equipped with N antennas, and the kth transmitter sends Lk independent data streams to the desired receiver. In the literature, there exist a variety of theoretically promising transceiver designs for the interference channel such...
Distributed antenna systems (DAS) add remote radio units with one or more antennas to enhance coverage and capacity in cellular systems. DAS works by connecting the remote radio units to the base station via a high bandwidth and low latency link. This paper analyzes multiuser multiple input multiple output (MIMO) DAS and compares it with multiuser MIMO communication without DAS in terms of per-user...
This paper studies the receiver structure of double STTD system with 4×2 antenna configuration. A new scheme of adaptive power allocation for double STTD is proposed, which minimizes the mean BER of double STTD system. Simulation results show that the adaptive power allocation scheme outperforms significantly traditional equal power allocation for double STTD system.
This paper studies the receiver structure of double STTD system with 4??2 antenna configuration. Simple receivers for double STTD are proposed, which requires no matrix inversion or iteration ordering. Simulation results show that the performance loss proposed receiver for double STTD is very small and the computation complexity is very low.

In this paper, we deliver the diagonalization methods for the single user and multi-user D-STTD (Double Space Time Transmission Diversity) system. A single user D-STTD system is that one transmitter sends four streams to one receiver and a multi-user D-STTD system is that one transmitter sends four streams to two receivers. In the two scenarios, we utilize the special structure of HHH of D-STTD system...
In conventional MIMO cellular systems, the spatial transmission mode, e.g. spatial multiplexing or transmit diversity, is chosen independently in each cell. Unfortunately, the optimum transmission mode for users that are interference limited depends to a large extent on the transmission mode used by interfering base stations. This paper proposes interference-aware link adaptation where base stations...
Limited feedback enables the practical use of channel state information in single user and multiple user MIMO (multiple input multiple output) wireless communication systems. Using the limited feedback concept, channel state information at the receiver is quantized by choosing a representative element from a codebook known to both the receiver and transmitter. Unfortunately, achieving the high resolution...
Orthogonal frequency division multiple access (OFDMA) transmission has been chosen for the next generation of wireless networks. Multiple input multiple output (MIMO) techniques are well suited for OFDMA and will be used for increased transmission efficiency for both downlink and uplink. In this paper we focus on space division multiple access (SDMA) techniques for the uplink of such a network. In...
