Abstract: A coherent reverse channel, a per-chip spreading function, orthogonal spreading functions and a time alignment of all traffic channels are implemented such that the main signal of each channel arrives at a base-station within a fraction of a chip of one another in accordance with the invention. With this, the orthogonality among all channels is maintained, and, when demodulated, all channels except the channel of interest provides a cross-correlation of substantially zero with respect to the remaining signals.

Abstract: A spread-spectrum noise canceller (182) is provided. A received phase and a received amplitude for a first (216) and a second (236) component of a received spread-spectrum signal (200) is determined. The second component (236) is structurally similar to [a replica of] the first component (216), but differs by being received at a different time, being transmitted along a different path, or having a different phase [which was received at a different time]. In addition, the spread-spectrum signal (200) includes a first and a second known signal. A portion of a spread-spectrum noise signal in the received signal (200) is canceled by generating an estimated signal (270) by spreading (260) the second known signal at the second component received phase (204) with the first known signal at the first component received phase (224) and adjusting a gain (268) of an integrated form of the spread second known signal as a function of the received amplitudes of the first (216) and the second (236) components. Subsequently, the second known signal is processed out of the received spread-spectrum signal (200) by subtracting (166) the estimated signal (270) from a demodulated form (216, 236) of the received spread-spectrum signal (200).

Abstract: The method includes the steps of receiving (201), from a user, a first wireless voice transmission including a verbal description of a location. Using speech recognition, the first wireless voice transmission is converted (203) into a data representation of the location. The location may include a street address or a landmark name. Various types of services, particularly location-based services using the user's location, may be provided, including street address (407), directions from a starting location to a desired location (509), and emergency assistance (609).

Abstract: A method and apparatus for improved offset frequency estimation includes in a first embodiment a receiver (100) for coherent reception of a signal having known reference information, the receiver including an extractor (106) for extracting the reference information (107) from the signal, and an offset frequency estimator (110). The offset frequency estimator (110) includes a filter (121) for filtering the reference information and outputting a filtered reference sequence; a correlator (122, 124) for correlating the filtered reference sequence against a predetermined reference signal to form correlation values; and a peak detector (126) for determining an offset frequency estimate (131) from the correlation values. Other embodiments are also shown.

Abstract: A wireless communication device (100) can be handed off while operating in the slotted mode of a CDMA system. The wireless communication device (100) stores, prior to entering slotted mode, an Active Set including at least one active pilot and a Neighbor Set including a plurality of neighbor pilots. At least one receiver searcher (109) scans the at least one active pilot and at least one of the plurality of neighbor pilots prior to an assigned slot. A logic and control circuit (113) includes in the Active Set, prior to the assigned slot, at least two pilots of the at least one active pilot and the at least one of the plurality of neighbor pilots scanned prior the assigned slot. At least two of a plurality of receiver fingers (107) simultaneously monitor the Paging Channels of the at least two pilots during the assigned slot.

Abstract: A method of reducing interference within a cellular system (10) by partitioning a designated frequency spectrum within a service coverage area (11, 12, 13, 14, 15, 16, or 17) into a first and at least second spectrum inclusive of the designated frequency spectrum and each with an associated power level. Assignment of communication units to a spectrum and power level are based upon distance from the base site (as determined through signal strength measurements). The spectral content of spectra in adjacent service coverage areas is adjusted to include non-coincidental frequencies.
