This prior art search report presents the mappings of the various elements of claim 1 of U.S. RE42,219 (‘219 Patent), titled “Multiple-input multiple-output (MIMO) spread spectrum system and method”, from assignee Harmony Licensing LLC, published on 15 March 2011.
This patent relates to antennas, specifically to reducing the effects of shadowing or the blocking and attenuating of transmitted signals from a multipath environment. In multiple-input multiple-output (MIMO) systems, combining received signals at the receiving side can provide better signals. Each receiver antenna is coupled to filters having impulse responses matched to the chip-sequence signals of the spread-spectrum signals. A RAKE and space-diversity combiner combines the detected spread-spectrum signals and the detected multipath-spread spectrum signals to generate a plurality of combined signals.
