This paper presents the channel gain estimation algorithm for the MIMO-OFDM system under the high-speed movement environments. This method aims to achieve robust the MIMO-OFDM channel gain estimation using only the Kalman filter from the canonical state space models with: (a) a state equation composed of the channel gain and the colored driving source, and (b) an observation equation composed of the...
This study deals with pilot-aided multi-path channel estimation for orthogonal frequency division multiplexing (OFDM) systems under slow to moderate fading conditions. Some algorithms exploit the channel time-domain correlation by using Kalman filters (KFs) to track the channel multi-path complex amplitudes (CAs), assuming a primary acquisition of the delays. Recently, it was shown that less complex...
Filter bank-based multicarrier (FBMC) techniques have attracted a lot of interest in the last decade as a competitive alternative to the long established OFDM, particularly in wireless applications. Their potential stems from their increased ability to carrying a flexible spectrum shaping together with a major increase in spectral efficiency and robustness to synchronization requirements, features...
