This paper presents an overview of recent progressin the area of multiple-input–multiple-output (MIMO) space–timecoded wireless systems. After some background on the researchleading to the discovery of the enormous potential of MIMOwireless links, we highlight the different classes of techniquesand algorithms proposed which attempt to realize the variousbenefits of MIMO including spatial multiplexing and space–timecoding schemes. These algorithms are often derived and analyzedunder ideal independent fading conditions. We present the stateof the art in channel modeling and measurements, leading to abetter understanding of actual MIMO gains. Finally, the paperaddresses current questions regarding the integration of MIMOlinks in practical wireless systems and standards.
