摘要： A method for detecting symbols is provided in a communication system. Symbols are received simultaneously through multiple spreading code channels. The received symbols are detected by processing one received symbol at a time, calculating reliability metrics recursively from a symbol received through a first spreading code channel for each possibly transmitted symbol by comparing each possibly transmitted symbol with each rake receiver finger adapted to the received symbol at a time, and selecting, based on the reliability metrics, a number of most probable candidate symbols for further processing. The process then calculates reliability metrics from a symbol received through a second spreading code channel using the reliability metrics for the most probable candidates. The method utilizes effectively cross-correlation properties of the spreading codes associated with the spreading code channels.

摘要： A method for performing an acquisition to a code-modulated spread spectrum signal comprises receiving the transmitted signal, sampling the received signal to form samples, forming at least one reference code corresponding to a code used in the modulation and forming a non-coherent search matrix on the basis of said samples. The non-coherent search matrix comprises elements in at least a first and a second dimension. The first dimension of the non-coherent search matrix represents the same frequency deviation but different code phases of the received signal, and the second dimension of the non-coherent search matrix represents the same code phase but different frequency deviations of the received signal. Each element is addressable in the first dimension by a first index and in the second dimension by a second index.
