Abstract: A plurality of encrypted packets having common payload data are received, wherein each of the plurality of encrypted packets includes a corresponding parity check field, and wherein a corresponding parity check syndrome for each of the plurality of encrypted packets indicates at least one bit error. A payload portion of each of the plurality of encrypted packets is decrypted to generate a plurality of decrypted payload portions. At least one chase coding technique is used to generate a corrected decrypted payload, based on at least one candidate bit error position and further based on the corresponding parity check syndrome for at least one of the plurality of encrypted packets.

Abstract: A Bluetooth low energy (BLE) device receives advertising packets from an advertising BLE device. The BLE device filters the received advertising packets utilizing hardware to search for the advertiser. If the advertiser is not found by the hardware, the packet filtering continues utilizing firmware. Device identity information, comprising non-private and/or private device identities, of preferred BLE devices is partitioned to form a different white list for the hardware, firmware, and host, respectively, to concurrently support privacy and white listing. If the advertiser is found by the hardware, the hardware sends a response to the advertiser following a successful CRC check performed in the hardware. If the advertiser is found by the firmware, the device identity information of the advertiser is inserted in the white list for the hardware. The host may be awakened based on the device configuration and/or attribute type information of the received advertising packets.

Abstract: Various examples are provided for related to Bluetooth voice quality improvement. In one example, among others, a method includes determining whether a packet payload is received during a transmission period of a collocated interface based at least in part upon signaling from the collocated interface and replacing at least a portion of the payload with estimated payload data based at least in part upon whether the payload was received during the transmission period. In another example, a communication device includes a first interface that supports BT communications and a collocated second interface. The first interface is operable to replace at least a portion of a payload of a BT packet with estimated payload data based at least in part upon signaling from the second interface that indicates whether at least a portion of the BT packet was received during a transmission period of the second interface.

Abstract: Aspects of a method and system for Bluetooth conditional synchronization are provided. In this regard, a synchronization code of a piconet may be included in each transmitted Bluetooth packets and a portion of the received synchronization code may be used for a synchronization process. The received synchronization code may be selectively sampled at a Bluetooth device. The Bluetooth device may determine a puncturing pattern to detect selected samples in the received synchronization code. The punctured received synchronization code may correlate to a reference code derived from a Bluetooth device address of the master device. The correlation value may be compared to a predetermined threshold value to indicate a success or a failure of the synchronization process. The threshold value as well as the puncture pattern may be user specific or centrally controlled, and they may be programmed or updated dynamically based on various conditions.

Abstract: In a radio comprising a transmitter and a receiver, transmission and reception of signals may be controlled based on received signal strength measurements from a signal strength indicator module and transmitted signal strength measurements from the signal strength indicator module. For the transmitted signal strength measurements, the shared signal strength indicator module may measure signal strength of a signal output by a power amplifier. For the received signal strength measurements, the shared signal strength indicator module may measure signal strength of a received signal. A capacitance coupled to an output of the power amplifier may be configured based on a frequency of the signal output by the power amplifier. A gain of the power amplifier may be controlled based on the transmitted signal strength measurements. For the transmitted signal strength measurements, an analog-to-digital converter may process the signal output by the power amplifier.

Abstract: A method and system for reducing data loss in digital communication between asynchronous digital devices. The method includes generating a first data transmission stream using a transmitter device, the first data stream synchronous to a first clock signal. A second data transmission stream is then generated using the transmitter device, wherein the second data transmission stream is a copy of the first data stream with a phase shift. A determination is then made as to whether the phase of the first clock signal is within a predetermined amount of the phase of a receiver clock signal of a receiver device, wherein the receiver clock signal is used by the receiver device to sample received data. The first data stream is transmitted to the receiver device when the phase of the first clock signal differs from the phase of the second clock signal by greater than the predetermined amount.
