receiver adapted for receiving multipath signals, as well as method and equipment for decoding multipath signals

摘要

Patent: "Trajectory Detection for Multipath Wireless Receiver". A wireless receiver receiving multipath walsh code symbols determines which of the collectors (402, 410) has captured or "locked" a signal. Correlation energy measurements between the received signal and all possible symbols are stored in energy storage units (404, 412). the actual signals are combined in the combiner (408). a maximum determiner (416) determines the most likely combined symbol and an index for such symbol is fed back to the energy storage units. Locking detectors (406, 414) use metering for such a back-fed symbol to determine if the collector has locked in a path. Such determination is used to decide whether the next signal detected by such a collector should be applied to the combiner.
