Originální abstrakt

Transmission over Multiple Input Multiple Output (MIMO) radio channels is considered. This paper investigates the impact of imperfect CSI (Channel State Information) on non-orthogonal space-time block coded system. Recent works describe impact of phase or amplitude error on the space-time block coded systems. In this paper it is shown how temporary imperfect knowledge of CSI can degrade bit error rate performance of the non-orthogonal space-time block codes in fast varying channels and how it can be improved by linear or lowpass filter interpolation of the MIMO coefficients.
