Abstract	Hybrid MIMO systems are defined as a combination of architectures designed to achieve both multiplexing gain (such as VBLAST), and diversity gain, (such as STBC). In these systems the detection can be performed with an ordered successive interference cancellation (OSIC) based on SQRD algorithm, in which the layers with diversity are decoded first. In this paper we introduce a new way to represent hybrid systems, in which the detection process is carried out in a unified manner for both spatial and diversity transmitted symbols, using an OSIC algorithm, but symbol by symbol, just as single VBLAST systems performs. We show that within this approach, linear dispersion (LD) coding has been actually generated, that allows the use of LD theory to determine the performance achieved by the hybrid system. Therefore a bridge between hybrid systems and LD codes has been established.
