Patent number: 10887048Abstract: A sink device is configured to establish a Bluetooth connection with a source device. The sink device receives a transmission from the source device that includes a plurality of data blocks, an item of check information, and a plurality of parity blocks during a transmission time duration. The sink device determines, prior to receiving an entirety of the transmission, whether at least one of received data blocks includes an error based on at least the item of check information and, when the at least one of the received data blocks includes the error and prior to receiving all of the plurality of parity blocks, the sink device performs an error correction operation on a first one of the received data blocks based on a first one of the parity blocks.Type: GrantFiled: September 26, 2019Date of Patent: January 5, 2021Assignee: Apple Inc.Inventors: Alon Paycher, Naftali Sommer, Tal Inbar, Sriram Hariharan, Axel Berny, Roi Faust, Eli Ochayon, Sreeraman Anantharaman

Patent number: 9843378Abstract: A wireless transceiver contains a receiver and a transmitter. The receiver is operable in single-input single-output (SISO) mode as well as multiple-input multiple-output (MIMO) mode, and contains a pair of in-phase and quadrature signal processing chains and a baseband processor. In SISO mode, each of the processing chains in the pair is connected to receive a same modulated signal as input, and generates respective baseband outputs. The baseband processor processes the baseband outputs to demodulate the modulated signal. In MIMO mode, the signal processing chains in the pair receive different modulated signals and generate corresponding down-converted signals. The baseband processor processes the down-converted signals to demodulate the respective modulated signals received by the receiver. Corresponding techniques to provide MIMO in addition to SISO capabilities are implemented in the transmitter also.Type: GrantFiled: July 23, 2010Date of Patent: December 12, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Gregory Lerner, Nir E J Tal, Ronen Shaul Isaac, Roi Faust

Patent number: 8724649Abstract: A novel and useful apparatus for and method of distributed coexistence for mitigating interference in a single chip radio and/or a multi-radio (i.e. multi-transceiver) communications device. The invention enables coexistence ‘friendly’ radio IPs having frequency agility in that they are capable of shifting their clock frequencies thereby avoiding frequency bands of potential victim radios. Frequency agility on the aggressor radio side (rather than by mitigating the effect of interference on the victim radio side) prevents harmonics from the aggressor's clock scheme from falling in the operating frequency band of the victim radio, and in turn causing degradation to its performance. Each aggressor radio, based on information received from other radios, configures the root clock frequency of its RX and/or TX chain clock generation circuits.Type: GrantFiled: December 1, 2008Date of Patent: May 13, 2014Assignee: Texas Instruments IncorporatedInventors: Nir Tal, Yaniv Tzoreff, Moran Amidan, Gregory Lerner, Ronen Isaac, Roi Faust

Patent number: 8175549Abstract: A novel and useful apparatus for and method of closed loop IQ calibration for use in a transmitter. The IQ calibration mechanism functions to provide calibration of IQ imbalance in the presence of real world RF impairments. An iterative process is used to update the gain and phase mismatch values whereby the metrics are calculated in a differential manner without the need for calculation absolute imbalance values. At each iteration, updating the gain and phase mismatch estimate requires only the direction of the correction to be determined. The direction of the correction is calculated using only the differences between output power measurements. The updated gain and phase mismatch estimates are used to update an IQ correction matrix. This process is repeated until a desired stopping criterion is reached. Gear shifting is used to ensure quick convergence of the algorithm while providing the ability to achieve any desired level of accuracy.Type: GrantFiled: October 17, 2008Date of Patent: May 8, 2012Assignee: Texas Instruments IncorporatedInventors: Roi Faust, Gregory Lerner, Nir Tal
