Smart Antennas for Next Generation Wireless Systems

The adoption of multiple antenna techniques in future wireless systems is expected to have a significant impact on the efficient use of the spectrum, the minimisation of the cost of establishing new wireless networks, the enhancement of the quality of service, and the realisation of reconfig-urable, robust, and transparent operation across multitech-nology wireless networks. Although a consider...

Adaptive Antennas and Mimo Systems for Wireless Systems

Coupled with a robust and efficient OFDM air interface, MIMO technologies lead to a very compelling high-speed data downlink solution for future wireless systems. This article presents Nortel Networks’ MIMO-OFDM concept prototype and measured performance results. This prototype has been developed in the framework of a Nortel Networks system concept for 3G evolution systems and next-generation w...
