Demodulation element assignment in a system capable of receiving multiple signals
TLDR
In this article, a receiver having a plurality of demodulation elements (204A, 204B, 204C) is considered, and the number of reassignments is controlled so that excessive data is not lost during the reassignment process.Abstract:
In a receiver having a plurality of demodulation elements (204A, 204B, 204C), a method of assigning the plurality of demodulation element to a set of available signals. A first method emphasizes diversity of transmitting devices so that power control is optimal. A second method emphasizes the maximum signal strength available to produce aggregate maximum signal strength. Both methods control the number of reassignments so that excessive data is not lost during the reassignment process. The apparatus comprises the plurality of demodulation elements (204A, 204B, 204C), at least one searcher element (202), and a controller (200).read more
