From: Novel polar-coded space-time transmit diversity scheme over Rician fading MIMO channels
BER performance of polar-coded STTD system corresponding to 2 × 2 MIMO. The bit error rate performance of polar-coded STTD system with two transmit antennas and two receive antennas. The Rician K-factors are various, which include the positive infinity (AWGN) and negative infinity (Rayleigh)
