  • Patent number: 6959035
    Abstract: A Code Division Multiple Access (CDMA) post-correlation processing system (12) for delay locked loop processing reduces the control data rate into a delay locked loop (DLL) processor and the number of required interpolation operations by executing a portion of the interpolation operations at a symbol data rate rather than at a chiprate. Specifically, an interpolator (16) generates time shifted chip samples based on input CDMA chip samples. First and second correlators (22, 24) extract ontime control and data symbol samples, respectively, from ontime input CDMA chip samples. A third correlator (26) extracts first non-ontime control symbol samples from non-ontime CDMA chip samples. The first non-ontime control symbol samples are then input with the ontime control symbol samples to a post-correlation interpolator (28) operating at a symbol rate to generate second non-ontime symbol samples necessary for Delay Locked Loop (DLL) processing.

    Abstract: An electronically tunable planar antenna 12, a wireless communication device 10, and a method of tuning an antenna 12 in which a high band element 28 and a low band element 26 each have a resonant center frequency. At any given time, the antenna 12 has two center resonant frequencies and thus allows the device to operate at two frequencies simultaneously. In addition, tuning circuits 38, 36 are connected to the low band element 26 and the high band element 28, respectively. The tuning circuits 36, 38 electronically change the resonant center frequency of the corresponding element 26, 28. Accordingly, in the device 10 the method, and the antenna one or both of the center frequencies can be changed to permit operation at more than two frequencies.

  • Patent number: 6825736
    Abstract: A level detector (110, 104) and corresponding method detects (602) whether an output signal level of a VCO (102) is within a window bounded by minimum and maximum thresholds. When the output signal level is not within the window, a loop-control element (108) closes (604) an AGC loop of the VCO and controls the gain of the VCO with a gain-control signal that tracks an AGC bias signal. When the output signal level is within the window, the loop-control element opens (606) the AGC loop and controls the gain with a fixed bias signal derived from the AGC bias signal at the time the AGC loop is opened.

  • Patent number: 6812802
    Abstract: A rectifier (306) rectifies (402) an output signal of a VCO (302) to produce an envelope signal proportional to an amplitude of the output signal. An integrator (308) integrates (404) the envelope signal to produce a comparison signal, such that, in response to a change in the envelope signal, during a first mode of operation of the VCO, the comparison signal is allowed to change at a first rate, and, during a second mode of operation of the VCO, the comparison signal is allowed to change at a second rate different from the first rate. A comparator (310) compares (406) the comparison signal with a reference signal (316) to produce a bias signal, and controls (408) a gain of the VCO with the bias signal.

  • Patent number: 6813257
    Abstract: A CDMA cellular communications network (400, FIG. 4) includes one or more aircraft (410), which relay pilot channel and control channel signals between base transceiver stations (BTS's 406, 413) and subscriber units (401). Over the control channel, the BTS transmits a handoff candidate list to the subscriber units. The handoff candidate list identifies candidate BTS's to which the subscriber unit, theoretically, could hand off. In addition, the list indicates at which offsets the subscriber units should search for short codes transmitted by the candidate BTS's over the pilot channel. Based on the path length between the BTS, aircraft, and subscriber unit, the candidate BTS's actually generate their short codes at an offset that is equal to or earlier than the offset reported to the subscriber unit by some delta. In addition, the BTS's can impose a variable delay on the generated short code bits to compensate for variations in the path delay as the aircraft flies in its flight pattern.

  • Patent number: 6804515
    Abstract: A wireless communications system infrastructure includes an integrated unit of RF and switch components mounted on a transportable platform for providing a communications link to a public switched telephone network. An airplane for executing a predetermined flight pattern includes a repeater for communicating with the integrated unit of RF and switch components and provides a link between the integrated RF and switch components and operational handsets within a repeater geographic area of coverage corresponding to the flight pattern. The wireless communications system infrastructure is therefore capable of being positioned strategically with respect to terrestrial cell stations and with respect to a flight pattern of the plane carrying the repeater to provide coverage to areas that otherwise may be out of range of an airborne repeater and conventional wireless system infrastructure components.

  • Patent number: 6795191
    Abstract: A print media sensor (10) according to the present invention determines a print medium type by utilizing an ultrasonic transducer (22) to vibrate a print medium (28) at a resonant frequency of the print medium (28). The print medium (28) is irradiated with light from an LED (20). Sensors (24, 26) measure the amount of light reflected from and transmitted through the print medium (28) while it is being vibrated at the resonant frequency. The ratio of the reflected to transmitted light is compared to a stored table of ratios that are associated with the resonant frequencies of specific print medium types and print medium ink volume and application rates. The results of these comparisons are used to determine the print medium type and the associated ink volume and application rate to be used for printing on the print medium (28).

  • Patent number: 6795699
    Abstract: A method of locating a billing area associated with a cell phone call initiated in an airborne cellular communications system enables service providers to more accurately identify system user locations within the system's area of coverage. In operation, propagation delay and beam number location of an initiated call are identified to determine a current handset radial beam location. The propagation delay is then mapped to a stored closest corresponding radial geographic billing location, and the call is then associated with the closest corresponding radial geographic billing location. Additional system accuracy may be provided by determining azimuthal position within a beam footprint by determining a handoff location of a signal from a first beam to a second beam, and then mapping handoff information to a closest corresponding azimuthal geographic billing location. Both the closest corresponding radial and azimuthal geographic billing locations are then used to identify a current handset location.
