    Abstract

    In this contribution we introduce a modeling approach for the influence of radio-impairments in (multi-antenna) wireless communication systems. This method, differently from previous approaches, regards two phases: a stage where the impairments are severe and one where the influence is less critical, which enables the inclusion of the impact of power-save-modes and transmitter/receiver mode switching. The error model includes an additive and a rotational part, both implemented in the transmitter as well as in the receiver. As an example, it is shown how phase noise maps onto the introduced error model. As a test case, a multiple-input multiple-output orthogonal frequency division multiplexing (MIMO OFDM) system based on coherent detection is regarded. The system applies zero-forcing as detection method. Analytical expression is derived for the probability of error of such a system impaired by the introduced error model. Finally, numerical results from simulations are shown, which confirm the results from the analytical study
