    摘要: A method and apparatus for modular authentication of a wireless communication device (120) including a portable communication device (210) and a wireless communication module (220) coupleable thereto is disclosed. When the wireless communication module (220) receives information (706) from the portable communication device (210), it determines whether the information received is authentic information (710) and operates together with the portable communication device (210) as a wireless communication device (120) in a communication system (100) in response to the information received being authentic information (720). In addition, a method and apparatus is disclosed for checking subsidy lock in a wireless communication device (120) capable of operating in a communication system (100), the wireless communication device comprising a first module (210), a second module (220) and a subscriber identity module (230) coupled to the first and second modules (210, 220). The first and second modules (210, 220) independently determine whether subsidy lock information stored in the subscriber identity module (230) corresponds to correct subsidy lock information (614, 618), and set a state of the wireless communication device (120) as operable in the communication system (100) in response to determining that the subsidy lock information stored in the subscriber identity module (230) corresponds to the correct subsidy lock information (614, 618).

    摘要: An electronic apparatus is provided having a front side and a rear side oriented in opposite directions along a first axis, and a right-side and a left-side oriented in opposite directions along a second axis that is perpendicular to the first axis. A null control signal is generated based on an imaging signal. A first microphone located near the right-side of an electronic apparatus generates a first signal and a second microphone located near the left-side of the electronic apparatus generates a second signal. The first and second signals are processed, based on the null control signal, to generate a right beamformed audio signal having a first directional pattern having at least one first null, and a left beamformed audio signal having a second directional pattern having at least one second null. A first angular location (α) of the at least one first null and a second angular location (β) of the at least one second null are steered based on the null control signal.

    摘要: At least two microphones generate wideband electrical audio signals in response to incoming sound waves, and the wideband audio signals are filtered to generate low band signals and high band signals. From the low band signals, low band beamformed signals are generated, and the low band beamformed signals are combined with the high band signals to generate modified wideband audio signals. In one implementation, an electronic apparatus is provided that includes a microphone array, a crossover, a beamformer module, and a combiner module. The microphone array has at least two pressure microphones that generate wideband electrical audio signals in response to incoming sound waves. The crossover generates low band signals and high band signals from the wideband electrical audio signals. The beamformer module generates low band beamformed signals from the low band signals. The combiner module combines the high band signals and the low band beamformed signals to generate modified wideband audio signals.

    摘要: A method (200) of cancelling echo in a duplex communication device (100). The method can include detecting a level of noise present on an uplink signal path (104), generating a noise classifier (194) based on the detected level of noise, detecting whether uplink audio is present on the uplink signal path (104) and detecting whether downlink audio is present on a downlink signal path (102). The method further can include generating a double talk flag (136) based at least on the noise classifier, whether uplink audio is present on the uplink signal path, and whether downlink audio is present on the downlink signal path. In addition, the double talk flag, the noise classifier and an uplink signal can be processed to generate an output signal (120) having reduced echo.
