Joint MIMO Channel Tracking and Symbol Decoding Using Kalman Filtering
Abstract
In this paper, the problem of channel tracking is considered for multiple-input multiple-output (MIMO) communication systems where the MIMO channel is time-varying. We consider a class of MIMO systems where orthogonal space-time block codes are used as the underlying space-time coding schemes. For such systems, a two-step MIMO channel tracking algorithm is proposed. As the first step, Kalman filtering is used to obtain an initial channel …
