This paper proposes a general framework for the calculation of space-frequency correlation at the receiver in time-invariant frequency selective channel environments. The proposed framework incorporates antenna locations to capture the spatial information of the channel and a general joint angle-delay power distribution to capture the frequency selectivity of the multipath channel. To demonstrate the strength of the proposed framework, we apply it on an orthogonal frequency division multiplexing (OFDM) system to obtain the space-frequency correlation between two antenna elements for two analytically derived joint angle-delay power distributions.
