Abstract: of the Invention An improved hands-free user-interactive control and dialing system is disclosed for use with a speech communications device. The control system (400) includes a dynamic noise suppressor (410), a speech recognizer (420) for implementing voice-control, a device controller (430) responsive to the speech recognizer for controlling operating parameters of the speech communications device (450) and for producing status information representing the operating status of the device, and a speech synthesizer (440) for providing reply information to the user as to the speech communications device operating status. In a mobile radiotelephone application, the spectral subtraction noise suppressor (414) is configured to improve the performance of the speech recognizer (424), the voice quality of the transmitted audio (417), and the audio switching operation of the vehicular speakerphone (460). The combination of noise processing, speech recognition, and speech synthesis provides a substantial improvement to prior art control systems.

Abstract: A portable electronic device (100) facilitates entry of user data and commands by detecting motion of the device (100). A display (112) is used to depict a plurality of user interface options (300, 500, 502). The user physically moves the device (100) to highlight and enter a desired character of data (302) or a command (504). For example, a virtual keypad (300) may be displayed, and when the device (100) is moved forward, backward, left, or right relative to the plane of the display (112) the next letter or number in that direction (or the opposite direction) may be highlighted. Then, by moving the device (100) downward (i.e., perpendicular to the plane of the display (112)) the highlighted letter or number may be entered as if it were typed on a real, dedicated keypad.

Abstract: Performance of a radiotelephone (104) in a CDMA communication system (100) is enhanced using a receiver searcher (114) that includes a matched filter (128) to capture the pilot energies of all receivable transmissions from a base station (102) and other nearby base stations. A detected PN sequence is compared with a predetermined PN sequence stored at the radiotelephone (104). The predetermined PN sequence includes, for example, the last 512 chips in the short PN sequence used for spreading the in-phase channel and the quadrature-phase channel.

Abstract: A radio subscriber unit (102) has a diversity receiver apparatus (106) including a first antenna (114) and a second antenna (116). A first representation (158) and a second representation (160) of a composite radio frequency (RF) signal are received from the first antenna (114) and the second antenna (116), respectively. The composite radio frequency (RF) signal includes a desired RF signal (156) and interfering signals (166). The desired RF signal (156) includes at least one coded pilot signal (Ec). A ratio (Ec/Io) (142) of the at least one coded pilot signal (Ec) to an estimate of the composite RF signal (Io) is determined responsive to receiving at least one of the first representation of the composite RF signal (158) and the second representation of the composite RF signal (160). A selected state of the first antenna(114) and the second antenna (116) is controlled responsive to at least one of the ratio (Ec/Io) (142) and an integrated received signal strength indication ( INTEGRAL RSSI) of the composite RF signal.

Abstract: A method, performed by a mobile station (119), prevents an active call from being dropped when the mobile station (119) suddenly transitions from a first coverage area (121) to a second coverage area (122) in a code division multiple access (CDMA) cellular radiotelephone system (100). The active call is determined (601) to be in danger of being dropped responsive to the mobile station (119) suddenly transitioning from the first coverage area (121) to the second coverage area (122). The first base station (115) is notified (602) that the active call is in danger of being dropped responsive to the step of determining (601). The active call with the first base station (115) is determined (603) to be in the process of being dropped responsive to the step of notifying (602). The active call is established (604) with the second base station (116) in the second coverage area (122) before the active call with the first base station (115) is dropped responsive to the step of determining (603).

Abstract: The power control apparatus of the present invention is comprised of a local oscillator signal path coupled to a mixer (106) through a variable attenuator (107) and an IF signal path coupled to the mixer (106) through two variable attenuators (108 and 109) coupled in series. The IF signal path attenuators (108 and 109) are controlled by digital control circuitry (111) while the local oscillator path attenuator (107) is controlled by the control circuitry through a level shifter (110). The power level of the signal generated by the mixing of these two signals is less than the conducted output of the radiotelephone's power amplifier.
