In this paper, a novel adaptive detection scheme for the case of Multiple-Input Multiple-Output (MIMO) Ricean channels with two transmit and receive antenna elements is presented. Our prime aim is to reduce the extensive complexity of Maximum-Likelihood (ML) detectors by developing an adaptive scheme which switches between a ML and a much simpler ZeroForcing (ZF) detector depending on the instantaneous spatial conditions. The kernel of the adaptive detector (AD) is a hard-decision criterion based on the condition number of the MIMO correlation matrix. It is demonstrated that the proposed scheme offers a remarkable reduction in terms of complexity along with a satisfactory performance when specifically designed antenna arrays are employed. © 2008 IEEE.
