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

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.
