Abstract

In this paper, we consider MISO systems with N transmit antennas and assume slowly time-varying channel. We select two out of N antennas and use Alamouti transmit diversity. At the receiver, we use zero-forcing detector and obtain expression of BER as a function of correlation (ρ) between two consecutive channel coefficients. We have also discussed some special cases, for example N = 2 transmit antennas and ρ = 1, and compared them with available results in literature.
