В настоящей работе рассматриваются возможные аппроксимации пропускной способности систем с множеством передающих и приемных антенн при наличии рэлеевских замираний в канале связи. Эти аппроксимации позволяют решить проблему оптимизации размещения ресурсов в радиосетях и других системах, используемых при обмене информацией, например, в системах контроля полета беспилотных летательных аппаратов. Предлагается аналитическая оценка точности определения пропускной способности при использовании предлагаемых аппроксимаций и демонстрируется точное совпадение с аналитическим определением пропускной способности.

This paper introduces functional approximations to the MIMO capacity over flat Rayleigh fading channels, which allow for analytical solutions to network resource optimization problems. This approximation allows to solve the problem of resource allocation optimization in radio networks and in other systems used to transfer information. The precision of the suggested approximations is assessed and is shown to provide a very close match to the exact capacity expression.
