Space-frequency code designs commonly rely on the assumption of independent and identically distributed (i.i.d.) Rayleigh channels. However real-world channels are space and tap correlated. In this paper, we study the impact of spatial and tap correlations on the performance of space-frequency codes. We propose a way to quantify the diversity achieved by any space-frequency code over Rayleigh fading channels with fullrank channel correlation. We show that in order to improve the coding gain, a block interleaver should be used instead of the commonly assumed random interleaver. Finally in order to improve the robustness of space-frequency coding in the presence of space-tap correlated channels, a new design criterion that takes into account the non-idealities of the channel is proposed. No channel knowledge is assumed at the transmitter.
