A frequency synthesizer includes: a phase detector, a loop filter, a controllable oscillator, a frequency divider, and a sigma-delta modulator for providing the division factor according to an integral part and a fractional part. The sigma-delta modulator includes a controller for providing a first digital value, a second digital value and a third digital value; a first adder for combining the second digital value, the third digital value, and a digital feedback value to generate a combination result; a quantizer for quantizing the combination result to generate a quantization value; a second adder for combining the first digital value and the quantization value to generate the division factor; and a multiplier for multiplying the quantization value by a constant multiplication factor; wherein the controller adjusts the third digital value in response to the reference signal for making an output frequency resolution substantially fixed.

The present invention relates to a method for controlling transmissions of a batteryless device (1) operating in a wireless network, the method comprising the following steps: the batteryless device (1) transmitting a frame including elements for controlling operation of a remote device (2a), or controlled device, the batteryless device being configured with a predetermined number of planned retransmissions of the control frame, the batteryless device sensing a change in the physical phenomenon induced by operation of the controlled device (2a), the batteryless device determining, based on the sensing step, the success or failure of the frame transmission, in case the transmission has succeeded, the batteryless device omitting further retransmissions of the control frame. The present invention also relates to a batteryless device carrying out such method.

The disclosure provides a method and device for implementing Viterbi decoding. The method comprises the following steps: calculating branch path measurement values of received code words and reference code words; parallel accumulating the branch path measurement values and measurement values corresponding to states to obtain accumulated values according to a state transition diagram, selecting a maximum accumulated value as a new measurement value of a next state, and saving all survival path selection results until data for decoding ends; and starting traceback from a final state to obtain decoded data according to the survival path selection results. In the disclosure, by modifying the traditional serial or serial-parallel mixed mode for calculating accumulated path measurement values to a multi-path fully-parallel calculation mode, the throughput rate of the system data is improved, and the decoding delay is merely in μs level.
