Comparison of precoding methods for broadband MIMO systems [PDF]
, 2009 In this paper we investigate non-linear precoding solutions for the problem of broadband multiple-input multipleoutput (MIMO) systems. Based on a broadband singular value decomposition (BSVD) we can decouple a broadband MIMO channel into independent ...

Wideband analysis of indoor MIMO channels [PDF]
, 2002 The application of MIMO communication systems in real environments will invariably require systems to operate over wideband channels. Although suitable techniques for processing wideband MIMO channels have been reported, their evaluation has mainly been ...

Физика волновых процессов и радиотехнические системыBackground. In wireless mobile communications, there are often situations when several radio transmitting devices operate on a single antenna system in several frequency bands, and therefore there is a need to create efficient multi-frequency antenna ...
