ABSTRACT:
In this talk, we propose a general framework that can be utilized to calculate the space-frequency correlation at the receiver in frequency selective channel environments. The proposed framework incorporates antenna locations to capture the spatial information of the channel and a joint angle-delay power distribution to capture the frequency selectivity of the multipath channel. To demonstrate the strength of this 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.
