Patent number: 10574393Abstract: The present disclosure describes methods and apparatuses for phase-based cyclic redundancy check (CRC) verification for wireless communication. In some aspects, a soft phase value and a sliced phase value are received for a symbol of a data packet, the data packet received via a wireless interface. An error measurement is determined for the symbol based on the soft phase value and the sliced phase value. The error measurement for the symbol is then compared to an error measurement threshold for detecting symbol-level errors in the data packet. Based on the error measurement exceeding an error measurement threshold, a bit error can be detected in the data packet, which may have passed CRC. By detecting the bit error despite a CRC pass, the bit error can be indicated to higher-level entity of the wireless interface. This can be effective to prevent the bit error from impairing operation of the higher-level entity.Type: GrantFiled: July 25, 2018Date of Patent: February 25, 2020Assignee: NXP USA, Inc.Inventors: Vijay Ganwani, Ankit Sethi, Sudhir Srinivasa, Sih-Yu Lin, Yui Lin

Patent number: 9414202Abstract: Improvements associated with determining a location of a station device are described. According to one improvement, a method is performed by a network device. The method includes receiving a response packet from a station device, multiple times, as received signals by switching between a plurality of antennas of the network device during reception of each occurrence of the response packet. The received signals are converted to corrupted orthogonal samples. The response packet is received from the station device a final time as a final response packet via a single antenna of the plurality of antennas. Ideal orthogonal samples are re-generated based at least in part on the final response packet. Signal phase information, embedded in the corrupted and ideal orthogonal samples, is converted into estimated locations of the station device.Type: GrantFiled: September 2, 2015Date of Patent: August 9, 2016Assignee: MARVELL INTERNATIONAL LTD.Inventors: Sudhir Srinivasa, Shuangqing Yuan, Li-Fu Jeng, Yui Lin, Hsun-Yao Jan

Patent number: 8897706Abstract: Different scan modes are provided for Bluetooth devices. In at least some embodiments, a narrowband scanning mode looks for signal energy on individual transmission frequencies at a time. By looking for signal energy rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A midband scanning mode looks for signal energy across multiple different frequencies at a time. Again, by looking for signal energy across multiple different frequencies rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A wideband scanning mode looks for signal energies across all relevant frequencies at a time. At least some embodiments enable a Bluetooth device to switch between scanning modes.Type: GrantFiled: February 1, 2013Date of Patent: November 25, 2014Assignee: Marvell International Ltd.Inventors: Yui Lin, Lawrence Tse, Poh Boon Leong, Minko Tsai, Robert Mack, Yungping Hsu

Patent number: 8787423Abstract: A system and method for frequency hopping precalibrates a subset of a plurality of channels, storing the channels' associated curves in a computer readable medium. Before hopping to a new channel, decision making circuitry can access the precalibrated curves. If the destination channel has an associated curve, then the system can use the values from that curve when hopping to a new channel. If the destination channel does not have an associated precalibrated curve, then the system can identify a closely situated channel with a precalibrated curve and use an offset value to settle at the destination channel. According to another aspect of the present invention, the offsets can be updated. According to a further aspect of the invention, the updated can be done dynamically.Type: GrantFiled: June 18, 2013Date of Patent: July 22, 2014Assignee: Marvell International Ltd.Inventors: Randy Tsang, Chun Geik Tan, Yui Lin, Meng Long
