Throughput enhancement for wireless communication systems using the multiple antenna technique MIMO

Abstract

One of the main goals in developing the next generation wireless communication system is increasing the data rates. A promising way to achieve this is the combination of multiple-input multiple-output (MIMO) signal processing with orthogonal frequency division multiplexing (OFDM). A test system has been built in which the OFDM based wireless LAN standard, IEEE 802.11a, is extended with MIMO. Initial measurements are performed in a typical office building and successful transmissions up to 162 Mb/s are demonstrated.
