Abstract:
1. A method for combining data from phase indeterminate data paths, comprising: receiving a wireless signal at a receiving device, the wireless signal including a plurality of path components, each path component carrying a main phase indeterminate data stream derived from an original data stream; splitting the received wireless signal into N signal copies and providing those N signal copies to N raking channels; correlating each of the N signal copies with N locally-generated signals, respectively, to generate N correlated signals, each of the N correlated signals carrying a phase indeterminate path data stream that estimates one of the main phase indeterminate data streams from one of the plurality of path components; synchronizing each of the N correlated signals to a system clock phase and a system clock frequency in the receiving device to generate N synchronized signals, each of the N synchronized signals carrying a synchronized path data stream; aligning the N synchronized signals to generate N aligned signals, each of the N aligned signals carrying an aligned path data stream that is normalized in time with respect to the other (N−1) aligned signals; and combining the N aligned signals to produce an estimated original data stream.
