摘要： PROBLEM TO BE SOLVED: To provide systems and techniques which enable a gated pilot signal to be acquired faster by checking neighbor pilot signals of a target pilot signal.SOLUTION: A subscriber station may frequency-lock onto a wrong pilot burst because a partial correlation exists between the wrong pilot burst and an adjacent pilot burst. Comparing the strength of the target pilot signal with the strength of neighbor 10 pilot signals enables the selection of the strongest pilot signal before the timely process of frequency locking and demodulation are initiated. Grouping pilot signals with the same symbol sequence and a pseudo-random noise increment apart enables quick acquisition of a gated pilot signal.

摘要： PROBLEM TO BE SOLVED: To provide a system and technique for enabling the faster acquisition of a gated pilot signal through a check of neighbor pilot signals of the target pilot signal.
SOLUTION: A subscriber station may perform frequency locking onto a wrong pilot burst because a partial correlation exists between a wrong pilot burst and an adjacent pilot burst. Comparing the strength of the target pilot signal with the strength of neighbor 10 system pilot signals enables the selection of the strongest pilot signal before the timely process of frequency locking and demodulation are initiated. Grouping pilot signals with the same symbol sequence and a pseudo-random noise increment apart enables the quick acquisition of a gated pilot signal.

摘要： PROBLEM TO BE SOLVED: To disclose systems and techniques for acquiring a gated pilot signal.
SOLUTION: A gated pilot signal can be acquired, by searching for a first gated pilot signal, deriving timing information from the search for the first gated pilot signal, and searching for a second gated pilot signal using the timing information. This is executed in a variety of fashions, including a receiver with a searcher configured to generate a bit sequence, a correlator configured for correlating a received signal with the bit sequence, and a processor configured to detect a first gated pilot signal as a function of the correlation, derive timing information from the first gated pilot signal and detect a second gated pilot signal, by using the timing information to control the bit sequence generated by the searcher.

摘要： A wireless remote unit performs SPS acquisition interleaved with receiving paging information over a wireless slotted paging channel and receiving data packets over a wireless data communication system. The remote unit tunes to a pilot channel, synchronizes to an internal clock of the wireless remote unit with a pilot signal transmitted over the pilot channel; and starts a search for SPS satellites after completing synchronization with the internal clock.

摘要： Techniques to efficiently attempt acquisition of a packet data system (e.g., an IS-856 system). If a terminal has acquired one or more channels in a voice/data system (e.g., an IS-2000 system), then it can attempt acquisition on channels in the packet data system that are co-located with the acquired channels in the voice/data system. Multiple acquisition modes may be used, and on-going acquisition attempts on the co-located channels may be performed using one acquisition mode at a time in order to reduce power consumption. Acquisition attempts may be performed in a “ping-pong” manner to improve the likelihood of acquisition. For a ping-pong search, an acquisition attempt is made on the most recently acquired channel prior to an acquisition attempt on each of the remaining channels. Received signal strength estimates may also be obtained for selected channels and may be used to determine whether or not to attempt acquisition on these channels.

摘要： A method for assigning tracking elements includes sorting a list of potential assignments according to a diversity criterion. In one example, a list of received signal instances is sorted first according to a measure of energy and then sorted again according to the diversity criterion. In a further embodiment, a demodulation element may be labeled available for assignment yet continue to output demodulated symbols in a locked state. Applications to a mobile station of a CDMA system for cellular telephony are discussed.

摘要： To access a first communication system, a terminal determines a transmission time for an access probe, an expected response time from the system, and a protected time interval based on the transmission time and/or expected response time. The terminal determines a starting time for sending the access probe such that the protected time interval does not overlap a tune-away interval in which the terminal is to monitor anther frequency/air-interface. This starting time may be set initially to the end of a prior access probe plus a pseudo-random wait duration and may be advanced forward or moved backward in time, if needed, by a time duration selected such that the protected time interval does not overlap the tune-away interval.
