Abstract :
Recent research has shown that multiple-input and multiple-output (MIMO) techniques can be used with orthogonal frequency division multiplexing (OFDM) for wideband transmission to mitigate intersymbol interference and enhance system capacity. In this paper, we present training sequence design and channel estimation for MIMO-OFDM systems. The effectiveness of the developed approaches are demonstrated by computer simulation examples.
