Abstract :
In this work formulations are designed to determine the spatial time correlation and the power spectrum of two mobile transceivers. In a CBD scenario, signals transmitted from the transceivers may travel longer path lengths due to reflective obstructions, and hence have longer delays than direct signals. This creates a reception problem due to the signal spread resulting in inter-symbol-interference. There is also a problem of trying to correlate two or more signals as the magnitudes and phases of these signals vary based on their specific path parameters. A means to estimate the signal at each receiver and account for the spatial time correlation of these signals is proposed in this paper.
