Patent attributes
Embodiments of the present invention provide methods and apparatuses for determining a parameter value for each of a plurality of communication signals received concurrently as a composite signal. The parameter value of each communication signal is within a corresponding parameter value set. Each parameter value set is disjoint from every other parameter value set. The parameter value for a particular communication signal is estimated by searching over the parameter value set corresponding to the particular communication signal. For one embodiment, the composite signal is received at a base station receiver of a SMDA/TMDA system that includes an array of spatially distributed antenna elements. To recover multiple communication signals at once, an embodiment of the invention segments the timing search window into disjoint intervals and invokes an instance of a basic receiver module for each timing search window.
