Channel Inversion Schemes with Compensation Network for Two-Element Compact Array in Multi-User MIMO

by Maxwell Oppong Afriyie, Obour Agyekum Kwame Opuni-Boachie and Affum Emmanuel Ampoma

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 4, Page # 26–31, 2017; DOI: 10.25046/aj020404

Abstract:

In this paper, we investigate the performance of channel inversion schemes for interference cancellation with compensation network in multi-user MIMO broadcasting channel. To achieve good performance, mutual coupling between two-element compact arrays is characterized by the receiving mutual impedance method (RMIM) to formulate the compensation network-operating matrix. A prototype of two-element compensation network with an…
