Publication number: 20240097725Abstract: Techniques for providing transmit redundancy for a wireless audio system, such as an in-ear monitor audio system, are discussed herein. Some embodiments may include tuning to a first wireless communication channel associated with a first carrier frequency to receive a radio frequency signal. Based on a determination that a communication channel condition for the first wireless communication channel satisfies a communication channel condition threshold, various embodiments include tuning to a second wireless communication channel associated with a second carrier frequency to receive the radio frequency signal, where the second carrier frequency is different from the first carrier frequency.Type: ApplicationFiled: September 14, 2023Publication date: March 21, 2024Inventors: Thomas J.

Patent number: 8755447Abstract: A communications system, e.g., a wireless microphone, incorporates a quadrature modulator system to reduce power consumption with respect to traditional approaches and is general in nature to support any two-dimensional digital technique. The quadrature modulator system comprises different subsystems, including a digital-analog transformation circuit, a baseband filter, and a quadrature modulator. The digital-analog transformation circuit converts discrete time samples to a continuous time signal, and further includes an oversampling noise-shaping modulator such as a sigma-delta modulator. The baseband filter then removes out-of-band energy including sampling images and quantization noise. Some of the circuit components may comprise discrete devices that may result in a reduction of power consumption for the quadrature modulator system. Alternatively, some or all of the circuit components may be incorporated in a single electronic device.Type: GrantFiled: December 22, 2010Date of Patent: June 17, 2014Assignee: Shure Acquisition Holdings, Inc.Inventors: Michael Joseph Goodson, Thomas J.

Patent number: 8285221Abstract: A method, a system and a device for implementing a scalable, self-calibrating and configuring, radio frequency head in a wireless base station that performs phase calibration for coherent combining of a pair of transmitter outputs. Configurable Antenna Calibration (CAC) logic initiates phase calibration for coherent combining by selecting a first configuration and triggering the transmission of a reference signal by radio frequency (RF) transmitters using different sub-carriers. The CAC logic generates a vector of phase values by comparing the reference signal with the respective signals received by a calibration receiver. The CAC logic also generates calibration coefficients for coherent combining by normalizing the phase values. In addition, a passive combiner mechanism is employed to implement coherent combining. The CAC logic performs calibration of smart antennas by providing calibration coefficients via a second configuration which utilizes both a calibration transmitter and the calibration receiver.Type: GrantFiled: August 31, 2009Date of Patent: October 9, 2012Assignee: Motorola Mobility LLCInventors: Thomas J.

Publication number: 20100111221Abstract: A method, wireless device, and wireless communication system manage quadrature and non-linear distortions in a transmitter system (100). A transmit data signal (235) is generated from a baseband data signal (202). The transmit data signal (235) can include one or more non-linear and/or quadrature distortions. An RF receiver circuit (238) receives the transmit data signal (235). A received signal, from the RF receiver circuit (238), includes a digital representation of the received transmit data signal (235). The received signal is statistically analyzed (404). A representation of each distortion of the one or more distortions is identified in the transmit data signal (235). At least one information signal (268) including an information set of distortion adjustments is generated. Distortion of the transmit data signal (235) is adjusted (410) based on the information set to reduce the one or more distortions in the transmit data signal (235).Type: ApplicationFiled: October 30, 2008Publication date: May 6, 2010Applicant: Motorola, Inc.Inventors: Gregory T.
