Abstract — Multicell MIMO is typically interferencelimited. Advanced signal-processing techniques like multiuser detection can be exploited to effectively combat co-channel interference and significantly improve system performance, provided perfect information for interferers is available

improve the system performance. Remarkably, such techniques literally exploit inter-cell interference by allowing the user data to be jointly processed by several interfering base stations, thus mimicking the benefits of a large virtual MIMO array. Multicell MIMO cooperation concepts are examined from

This paper presents an overview of recent progress in the area of multiple-input–multiple-output (MIMO) space–time coded wireless systems. After some background on the research leading to the discovery of the enormous potential of MIMO wireless links, we highlight the different classes

The use of space-division multiple access (SDMA) in the downlink of a multiuser multiple-input, multiple-output (MIMO) wireless communications network can provide a substantial gain in system throughput. The challenge in such multiuser systems is designing transmit vectors while considering the co

, the sum rate capacity scales like log log for large if perfect channel state information (CSI) is available at the transmitter, yet only logarithmically with if it is not. In systems with large, obtaining full CSI from all users may not be feasible. Since lack of CSI does not lead to multiuser gains

Abstract — A clustered base transceiver station (BTS) coordination strategy is proposed to realize the gains of multiuser MIMO communication in interference-limited cellular systems. In the proposed coordination strategy, users are divided into two groups: a full intra-cluster coordination group

at the BSs takes place via either standard single-cell processing or multicell processing (i.e., network MIMO). Closed and open-access femtocells are considered. Achievable per-cell sum-rates are derived in this setting for a linear cellular network. Overall, the analysis lends evidence to the performance

Abstract — In this paper, the spectral efficiency of multipleinput multiple-output (MIMO) systems operating in multicell frequency-flat fading environments is studied, for situations in which co-channel interference is the dominant channel impairment instead of ambient noise. The following
