Iterative receiver techniques, multiple-input – multiple-output (MIMO) processing, and

orthogonal frequency division multiplexing (OFDM) are amongst the key physical layer

technologies when aiming at higher spectral efficiency for a wireless communication system.

Special focus is put on iterative detection, decoding, and channel estimation for a MIMO-OFDM

system. After designing separately efficient algorithms for the detection, channel decoding, and

channel estimation, the objective is to optimize them to work together through optimizing the

activation schedules for soft-in soft-out (SfISfO) components.
