Abstract
A method/apparatus for use of the power/frequency characteristics of the candidate transmission for which the frequency must be allocated, the method/apparatus providing a power spectrum of the cumulative effect of the power/frequency characteristic of at least a portion of the existing transmission at a plurality of center frequencies within the frequency spectrum at the time of allocation, calculating allocation based on a first function of a combination of the power spectrum and the power/frequency of the candidate transmission, the first function being determined at different frequencies at the time of allocation, selecting a center frequency for the candidate transmission from the frequency spectrum based on a minimum value among the calculated allocation values or based on a calculated allocation value being below a first threshold value.
