METHOD AND APPARATUS FOR SELECTIVELY APPLYING INTERFERENCE CANCELLATION IN SPREAD SPECTRUM SYSTEMS

摘要

The present invention is directed to the selective provision of interference canceled signal streams (244a and 244b) to demodulating fingers (224a and 224b). Potential interfering signals paths (416) are identified. Signal streams having one or more potential interferering signals removed or canceled are created, and a correlation (238) is performed to determine whether the strength of a desired signal path increased as a result. If the correlation indicates that the strength of a desired signal path was increased by the interference signal cancellation, the interference canceled signal stream is provided to the demodulation finger (224a or 224b) assigned to track the desired signal path. If the correlation determines that the strength of the desired signal path did not increase as a result of performing interference cancellation, the raw or a different interference canceled signal stream is provided to the demodulation finger (224a or 224b).
