Abstract :
In this work a space-frequency block coding (SFBC) system is considered, which is compliant to the Long-Term-Evolution (LTE) specification. The Cramer-Rao bound (CRB) for the mimimum mean-square error (MMSE) of the channel estimator for an SFBC receiver is calculated comparing optimum versus robust Wiener interpolation. Further a lower bound on the bit error ratio (BER) of a binary phase-shift keying (BPSK) modulated SFBC system with imperfect channel state information (CSI) is derived. Finally the bit error outage (BEO) of the linear Alamouti combiner in presence of log-normal fading signal-to-noise ratio (SNR) is compared for different power delay profiles (PDP).
