摘要： A technique for improving open loop power control in spread spectrum telecommunications systems is disclosed. In a preferred embodiment, the technique is realized by transmitting at least one first access channel probe for a first message from a mobile station to a base station, wherein the transmission power level of each access channel probe in the at least one first access channel probe is increased until a base station acknowledgment is received for a specific access channel probe of the at least one first access channel probe at a first transmission power level. The first transmission power level is then stored at the mobile station. At least one second access channel probe for a second message is then transmitted from the mobile station to the base station, wherein the transmission power level of an initial access channel probe of the at least one second access channel probe for the second message is based upon the first transmission power level.

摘要： A method and system enable matched filters of a CDMA system to be simplified using a two stage search. A course stage and a fine stage jointly produce the locations(s) of received signal path-rays. In a first stage, an oversampled digital signal (240) is decimated, and the decimated signal (415) is applied to a matched filter (420) to eventually produce an approximate location (460). In a second stage, the oversampled signal (240) is shifted based on the determined approximate location (460) and then correlated to a generated code (440), and a more-exact location is selected from the outputs of the correlations (450). Alternatively, a shifted version of the generated code (440) is correlated to the oversampled signal (240), and the more-exact location is selected from the outputs of those correlations (450).
