摘要： A phase jump correction method and device are provided. The method includes: acquiring, by a receiving end, a sending end Training Sequences (TSs) generated by a sending end, and generating receiving end TSs by using a TS generation mode identical to a TS generation mode used at the sending end; determining a phase value of target TSs according to the acquired sending end TSs and the generated receiving end TSs; modifying, according to phase values of a plurality of non-target TSs of the receiving end, the phase value of the target TSs to obtain a modified phase value; and performing, according to the obtained modified phase value, phase jump correction on service data received from the sending end.

摘要： The present technology relates to a signal processing apparatus and method which can suppress increase in power consumption. In an aspect of the present technology, control data, which is for controlling frequency modulation to a carrier signal using digital data to be transmitted, and for suppressing a time average of a fluctuation amount of a frequency modulation amount more than a case of controlling the frequency modulation to the carrier signal using the digital data is generated, the frequency modulation is performed to the carrier signal on the basis of the generated control data, and the carrier signal to which the frequency modulation is performed is transmitted as a transmission signal. The present technology can be applied to, for example, a signal processing apparatus, a transmission apparatus, a reception apparatus, a communication apparatus, or an electronic apparatus having a transmission function, a reception function, or a communication function, or a computer which controls these.

摘要： Counter-clockwise and clockwise quadrant transitions are detected and accumulated with respect to a received complex signal over a certain time period. These transitions may then be compared in order to obtain information indicative of both a magnitude and phase of a frequency offset error. Additionally, zero-crossings of the received complex signal over the same certain time period are detected and accumulated. The accumulated crossings provide information indicative of frequency offset magnitude. The determined magnitude and phase of the frequency offset error may then be used to adjust a local oscillator frequency to provide for improved receiver performance.
