In this paper a novel channel inversion (CI) precoding scheme is introduced for the downlink of multiple input multiple output (MIMO) systems. The proposed technique outperforms conventional CI by exploiting some of the consequential inter- channel interference (ICI). It achieves this by applying partial channel inversion such that the constructive part of ICI is preserved and exploited while the...
A novel antenna selection scheme is introduced in conjunction with a partial linear preceding technique for downlink and point-to-point multiple input multiple output (MIMO) systems. The proposed technique outperforms conventional channel inversion (CI) linear preceding by utilizing part of the existing inter-channel interference (ICI) between the MIMO sub-channels. It applies partial sub-channel...
This paper introduces a novel channel inversion (CI) precoding scheme for the downlink of phase shift keying (PSK)-based multiple input multiple output (MIMO) systems. In contrast to common practice where knowledge of the interference is used to eliminate it, the main idea proposed here is to use this knowledge to glean benefit from the interference. It will be shown that the system performance can...
Multiple-input multiple-output (MIMO) systems are still attracting the attention of many researchers and designers for their promising improvements in performance and bandwidth efficiency. This paper presents a low-complexity precoding technique which aims to maximise the MIMO diversity at the receiver. The proposed technique achieves maximum diversity by matching the transmitted data symbols with...
