摘要： An apparatus (100) maintains a Pilot Set in a digital communication system that utilizes Code Division Multiple Access. The apparatus comprises a logic and control circuit (113) for providing instructions to a searcher receiver (109). The searcher receiver, in response to the instructions, sequentially scans active pilots, then candidate pilots, and then pre-candidate pilots. The scan of the pre-candidate pilots continues until all but a predetermined number of pre-candidate pilots have been promoted or demoted. Then the searcher receiver alternately scans the predetermined number of pre-candidate pilots and the neighbor pilots. The searcher receiver terminates alternate scans of the predetermined number of pre-candidate pilots and the neighbor pilots when a one of the neighbor pilots is promoted, and resumes the scan of the pre-candidate pilots.

摘要： A circuit (2) and method employing logic circuitry (30) and memory (40) identifies a reverse link limited channel (80). The logic circuitry (30) identifies a reverse link limited channel based on determining that an access probe failure occurred on a channel (64). The logic circuitry (30) causes the memory to store reverse link limited channel data (80) in response to the logic circuitry (30) determining that the access probe failure occurred. The reverse link limited channel data (80), for example, may be a channel identification associated with the channel (64), a base station identification associated with the channel (64), a location identification of the circuit (2) or any data suitable for identifying and adapting dynamically to the reverse link limited channel.

摘要： A wireless communication device 100 acquires a pilot channel before an assigned slot when the wireless communication device is operating in the slotted mode of a CDMA system. The wireless communication device comprises a searcher receiver 107 that determines the short-term average pilot strength of active and neighbor pilot channels. Finger receivers 107 determine the long-term average pilot strength of the active and neighbor pilot channels. A logic and control circuit 113 assigns the finger receivers to the pilot channels according to their short-term average pilot strength, determines if the long-term average pilot strength of a neighbor channel is greater than the active pilot channel's pilot strength, and determines to hand off to the neighbor pilot channel with the greater long-term average pilot strength. Moreover, an early detection correlation length can be dynamically adjusted according to the pilot strength of the active pilot channel to shorten the pilot acquisition process.

摘要： This invention relates to a method and apparatus for measuring the phase change of an output optical signal from a device. In one embodiment an input optical signal is split into first and second optical signals, and the first optical signal is passed through the device while applying an external stimulus to the device, to produce an output optical signal having a phase shift. The carrier frequency of the second optical signal is changed, and the output optical signal and the changed second optical signal are then combined. The combined signal is detected in accordance with the external stimulus applied to the device, and the phase change of the output signal of the device is measured as a function of the external stimulus applied to the device.
