Title: Modified Kalman Filters for Channel Estimation in Orthogonal Space-Time Coded Systems
Author: Loiola, MB
Lopes, RR
Romano, JMT
Abstract: We derive and analyze two modified Kalman channel estimators (KCE) for time-varying, flat, spatially correlated MIMO channels in systems employing orthogonal space-time block codes: the steady-state KCE, which is less complex than the KCE, and the fading memory KCE, which is more robust to model mismatch.
