Research Brief

Uses of dual- and triple-polarized antennas are promising solutions for realizing compact devices also robust against many imperfections as compared to spatially separated antenna systems. This research is aiming to model the dual- and triple-polarized MIMO channel and investigate the BER performance of orthogonal space-time block coding (OSTBC) in MIMO-OFDM systems using proposed dual- and triple-polarized MIMO channel models.
