Multiple-input multiple-output (MIMO) wireless systems, pioneered a decade ago, have by now become a mature and well-established research field. Consequently, MIMO technology has been increasingly attracting the attention of industry and standardization bodies over the past years, leading to the inclusion of MIMO concepts in standardized wireless systems like WiMAX, WiFi, and 3GPP/3GPP2. First MIMO products have begun to penetrate the WiFi market. However, current practical MIMO implementations are still far from theoretical performance limits because system designers are experiencing difficulties to reconcile the complexity of sophisticated MIMO techniques with the implementation constraints imposed by existing hardware. Thus, one of the main challenges in the realization of multiuser MIMO wireless systems - and in fact a critical factor for the success of MIMO in WiMAX, WiFi, and beyond 3G - is the efficient implementation of advanced MIMO concepts. Here, the goal is to devise tunable algorithms that use clever complexity reduction techniques (especially at the receiver side) to achieve graceful performance degradation. This special session intends to promote this important new thread in MIMO research by bringing together some of the top experts in the field. The planned contributions to this session range from recent work on reduced-complexity MIMO detection schemes (including modern sphere decoding and lattice reduction algorithms) to novel approaches for space-time codes that are designed with robustness issues and receiver complexity in mind.
