    • 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.

    • 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.

    • 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. The second data stream is transmitted to the receiver device when the phase of the first clock signal differs from the phase of the receiver clock signal by less than the predetermined amount such that jitter on the first clock signal and the receiver clock signal does not disrupt communication between the transmitter device and the receiver device.
    • 一种用于减少异步数字设备之间数字通信中的数据丢失的方法和系统。 该方法包括使用发射机设备产生与第一时钟信号同步的第一数据流的第一数据传输流。 然后使用发射机设备生成第二数据传输流,其中第二数据传输流是具有相移的第一数据流的副本。 然后确定第一时钟信号的相位是否在接收机设备的接收机时钟信号的相位的预定量内,其中接收机设备使用接收机时钟信号来采样接收到的数据。 当第一时钟信号的相位与第二时钟信号的相位不同于预定量时,第一数据流被发送到接收机设备。 当第一时钟信号的相位与接收机时钟信号的相位不同于预定量时,第二数据流被发送到接收机设备,使得第一时钟信号和接收机时钟信号上的抖动不会中断通信 在发射机设备和接收机设备之间。
