Distributed Transmission for Cooperative Multiuser Multiple-Input Multiple-Output (MIMO) Systems

Objective

Multiple-input multiple-output (MIMO) systems have become an important area of research, as they are shown to enable high data rate communications with great reliability over the wireless link. In particular for cellular networks, MIMO techniques are promising for achieving high capacity by exploiting the spatial and multi-user diversities inherent in the channel. In a MIMO cellular system, it is possible to further enhance the system capacity through cooperation.

The aim of this work is to investigate the feasibility of and characterize the gains from base station (BS) cooperation and develop cooperative transmission schemes for the downlink of a MIMO cellular system, where the base stations cooperate in the transmission of information to the users in the system. To characterize the gains from BS cooperation, the asymptotic growth rates of the system capacity with the number of users and the number of BS antennas will be derived and compared for systems with and without BS cooperation. In the case of BS cooperation, the system can be modelled as a single cell MIMO broadcast channel. Therefore, recent results in the literature on MIMO broadcast channels (BC) can be utilized. However, the extension of MIMO BC results to cooperative systems requires cooperation of all base stations, which is not feasible for practical cellular systems. Thus, it is of interest to investigate distributed transmission schemes that can be implemented with local information exchange between the neighbouring base stations.

In this work, information-theoretic limits of such schemes will be studied and novel distributed transmission algorithms for cooperative MIMO cellular networks will be developed. The performance of these algorithms will be studied through computer simulations. The results of this work will be important for the widespread adoption of MIMO technologies for next generation cellular systems and find some interesting applications in wireless ad-hoc and sensor networks.
