摘要： In a fixed cellular telephone system, the taking of a standard wireline telephone set off-hook triggers the establishment of a voice/traffic channel connection between a connected fixed cellular terminal and the cellular system switch. Digits of the telephone number of the party to which the call is directed are entered through the telephone set. These digits are then transmitted by the fixed cellular terminal to the serving cellular network switch as out of band data messages transported over a control channel supported by the established voice/traffic channel connection. The data message digits are then converted to dual tone multi-frequency (DTMF) tones, with the tones processed in a conventional manner to complete the call connection to the called party.

摘要： A method and apparatus for acquiring timing signals for use in a positioning receiver using timing assistance provided by a wireless communications system, such as cellular telephone system. A mobile terminal equipped with a positioning receiver operates in a wireless communications system having control channels and at least one traffic channel unsynchronized to the control channels. The mobile terminal camps on a first control channel in a first cell having a first time base associated therewith. While camped on the control channel, the mobile terminal establishes a local clock reference, internal to the mobile terminal, capable of tracking the first time base. The mobile terminal then operates on a first traffic channel that is unsynchronized to the first control channel and notes the difference in time bases between the control channel and the traffic channel. Either while camped on the control channel or while operating on the traffic channel, the mobile terminal receives TDMA-to-GPS relationship data, which is a measure of the offset between system time for the wireless communications system as expressed on particular control channel ('TDMA time') and the system time for the GPS system ('GPS time'). Thereafter, an accurate estimate of the GPS time is calculated in the mobile terminal based on the local clock reference and the TDMA-to-GPS relationship data. In some aspects, the local clock reference is updated based on the first traffic channel so as to minimize errors arising from timing drift.

摘要： A branched power amplifier circuit includes two or more amplifier segments or branches, each with a corresponding lossy modulator. The branched power amplifier may be dynamically resized by enabling different ones of its branches to deliver peak efficiency at a number of different amplifier output power levels. Each amplifier branch operates in a saturated mode and selectively amplifies an RF input signal. The lossy modulators provide either supply voltage or supply current modulation to corresponding amplifier branches, thus imparting highly linear amplitude modulation to the overall output signal generated by branched power amplifier, despite its saturated mode operation. The branched power amplifier circuit may be configured such that particular combinations of segments have peak efficiencies matched to the needs of one or more air interface standards used in wireless mobile communication systems.

摘要： An echo canceler in which effective transfer function coefficients of an adaptive echo-canceling filter are adjusted periodically to track changing system conditions. Periodic adjustment of the effective coefficients is accomplished using a set of more frequently adjusted update coefficients and an update gain which is varied based on a strategic and novel combination of system parameter measurements. By updating filtering coefficients periodically rather than continuously, and by making soft, fuzzy-logic-type decisions with respect to the magnitude of the update gain, exemplary embodiments optimize system speed and adaptability without sacrificing stability. Generally, relatively large update gains are applied in situations where only a far-end user is speaking and a near-end signal is relatively noise-free. However, in near-end single talk, double-talk, and high near-end noise situations, a more conservative approach is used so that the adaptive filter does not become unstable or cause distortion in the near-end speech and noise signals. In either event, the update gain is reduced as the adaptive filter converges to match a prevailing steady-state echo environment so that erroneous perturbations of an already properly-adapted filter are minimized. The decision as to whether to apply high or low update gains during periods of nonconvergence is based in part on a system status gauge comprising a ratio of a peak update coefficient value and a baseline update coefficient value. The system status gauge indicates, among other things, a level of system convergence. In exemplary embodiments, relatively high variable update gains are applied in unconverged, far-end single-talk situations by employing a modified normalized least-mean-squares (NLMS) algorithm. In other unconverged situations, the update gain is adjusted more conservatively based on a normalized version of the system status gauge. By dynamically providing relatively large update gains while being careful not to create system instabilities, the exemplary embodiments quickly and robustly adapt to successfully cancel echoes in a wide variety of system environments and conditions.

摘要： A fixed cellular interface system is disclosed that includes an interface system arranged between a standard telephone unit and a fixed cellular terminal. The interface system includes a voice prompt system, which can be programmed to generate speech using the native language for the geographical region involved. The voice prompt system detects the user of the POTS phone going 'off hook', and vocally prompts the user to enter the desired number followed by the '#' sign. The interface system converts the received '#' sign to a 'SEND' signal. The interface system transfers the dialled number followed by the 'send' signal to the fixed cellular terminal which initiates the call to the cellular system.
