    • Techniques for cancelling a disturbance signal from a PLL output signal. In an aspect, a cancellation signal is combined with the signal input to a VCO or DCO in the PLL. In a further aspect, the appropriate cancellation signal is derived by analyzing one or more signals within the PLL. The signals within the PLL may be correlated against one or more disturbance signal templates, such as a sinusoid having a known frequency, to derive one or more correlation coefficients. The coefficients may be applied to weight one or more disturbance synthesis functions to generate the cancellation signal. Further aspects provide for joint analysis, synthesis, and cancellation of signals having unknown frequency from the PLL output.
    • 从PLL输出信号中消除干扰信号的技术。 在一方面,消除信号与输入到PLL中的VCO或DCO的信号组合。 在另一方面,通过分析PLL内的一个或多个信号来导出适当的抵消信号。 PLL内的信号可以与一个或多个干扰信号模板(例如具有已知频率的正弦波)相关,以导出一个或多个相关系数。 可以应用系数来加权一个或多个干扰合成功能以产生消除信号。 其他方面提供了从PLL输出端对未知频率的信号的联合分析,合成和消除。

    • A digital phase-locked loop (DPLL) supporting two-point modulation is described. In one design, the DPLL includes a phase-to-digital converter and a loop filter operating in a loop, a first processing unit for a lowpass modulation path, and a second processing unit for a highpass modulation path. The first processing unit receives an input modulating signal and provides a first modulating signal to a first point inside the loop after the phase-to-digital converter and prior to the loop filter. The second processing unit receives the input modulating signal and provides a second modulating signal to a second point inside the loop after the loop filter. The first processing unit may include an accumulator that accumulates the input modulating signal to convert frequency to phase. The second processing unit may include a scaling unit that scales the input modulating signal with a variable gain.

    • Techniques for decimating a first periodic signal to generate a second periodic signal. In an exemplary embodiment, the first periodic signal is divided by a configurable integer ratio divider, and the output of the divider is delayed by a configurable fractional delay. The configurable fractional delay may be noise-shaped using, e.g., sigma-delta modulation techniques to spread the quantization noise of the fractional delay over a wide bandwidth. In an exemplary embodiment, the first and second periodic signals may be used to generate the transmit (TX) and receive (RX) local oscillator (LO) signals for a communications transceiver from a single phase-locked loop (PLL) output.

    • This disclosure is directed to techniques for voice and data transmission from a wireless communication device, such as mobile telephone handset. In accordance with the disclosure, a wireless communication provides a hybrid coupler that permits voice and data calls to be combined for transmission over a common air interface. When increased transmit power is required, the wireless communication device prioritizes the voice call over the data call. In this case, the voice call is sent over both the voice output branch and the data output branch, taking advantage of the power amplifier in each output branch chain to achieve a greater overall transmit power for the voice transmission. In this manner, the mobile subscriber unit independently and simultaneously handles data and voice calls under ordinary circumstances, but drops the data call and combines the voice and data output branches for voice transmission when increased transmit power is required for the voice transmission.
    • 本公开涉及用于来自诸如移动电话手持机的无线通信设备的语音和数据传输的技术。 根据本公开,无线通信提供混合耦合器,其允许组合语音和数据呼叫以在公共空中接口上传输。 当需要增加发射功率时,无线通信设备通过数据呼叫来优先处理语音呼叫。 在这种情况下,语音呼叫通过语音输出分支和数据输出分支发送,利用每个输出分支链中的功率放大器来实现用于语音传输的更大的总发射功率。 以这种方式,移动用户单元在通常情况下独立地并且同时处理数据和语音呼叫,但是当语音传输需要增加发射功率时,丢弃数据呼叫并组合用于语音传输的语音和数据输出分支。
