Preamble-based MMSE Channel Estimation with Low Pilot Overhead in MIMO-FBMC Systems

As is well-known, high pilot overhead in channel estimation is a critical problem due to the imaginary interference in multiple input multiple output (MIMO) employing filter bank multicarrier (FBMC) (MIMO-FBMC) systems. In this paper, we propose a novel preamble design with low overhead and present...
