    Abstract: Systems and techniques for gain control include amplifying a signal with an amplifier having a gain represented by one of a plurality of gain curves depending on a value of a parameter, the signal being amplified at a first one of the parameter values, and controlling the gain of the amplified signal from a predetermined gain curve relating to the gain curve of the amplifier for a second one of the parameter values by adjusting a gain control signal corresponding to a point on the predetermined gain curve as a function of the first one of the parameter values, and applying the adjusted gain control signal to the amplifier. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

    Abstract: Techniques to search for a gated pilot reference in a wireless communication system. In one method, an overall code space in which the pilot may be found is partitioned into a number of groups of code sets, with each code set representative of all possible chip offsets of a specific PN sequence. The groups are ordered based on the likelihood of detecting the pilot in each of the groups. The groups of code sets are then used to search for the pilot, one group at a time, starting with the group most likely to result in successful pilot acquisition and ending with the group least likely to result in successful pilot acquisition. The search is terminated upon successful acquisition. The pilot search may be performed using detect, dwell, and pull-in substages. The detect substage for one group may be performed in parallel with the pull-in substage for another group.

    Abstract: A method and apparatus is described for tracking the length of a sleep period within a mobile station using a sleep clock to precisely calibrate portions of the sleep period. The sleep period subdivided into a sequence of sub-periods each of known duration wherein the durations of the sub-periods are not necessarily integer multiples of cycles of the sleep clock. Elapsed time is tracked within each individual sub-period of the sleep period using an integer sleep counter which tracks whole cycles of the sleep clock. Then any remaining fractional portions of the cycles of the sleep mode clock not accounted for by the integer sleep counter are tracked using a fractional sleep counter. The fractional sleep coutner accumulates remaining fractional portions of sleep mode cycles from one sub-period to the next. A method and apparatus is also described for estimating frequency drift with a sleep clock signal used during a slotted paging mode of operation of a wireless mobile station. An initial frequency of the sleep clock signal is determined following power-up of the mobile station. A fixed frequency drift compensation factor representative of a difference between the initial frequency of the sleep clock signal and a pre-determined nominal frequency is then determined. A dynamic frequency error compensation factor representative of a difference between the initial frequency and a current frequency of the slow clock signal is estimated. Then, throughout the slotted mode of operation, new values for the dynamic frequency compensation factor are iteratively determined by using a loop filter.
