摘要： Selectively enabling an amplitude processing circuit and a phase processing circuit of a wireless station's polar receiver with respect to reception of a beacon signal. Such systems and methods may include sequentially demodulating symbols of the received beacon signal using at least the phase processing circuit to detect a traffic indication signal value in a data payload portion of the received beacon signal. Upon detecting a condition indicating no data traffic for the wireless station, the phase processing circuit may be turned off. The polar receiver may demodulate symbols of the received beacon signal and upon detecting a beacon preamble symbol sequence, shut off the amplitude processing circuit and set the amplitude to a fixed value. The phase processing circuit in conjunction with the fixed amplitude value may be used to demodulate symbols of the beacon signal.

摘要： A method and circuit for linearizing a frequency response of an oscillator controlled by a plurality of capacitor banks are disclosed. In the disclosed method, for each capacitor bank of at least two capacitor banks of the oscillator, a respective sensitivity characteristic of the capacitor bank is determined. Further, a set of reference output frequency control words (FCWs) for an associated set of frequencies of the oscillator are determined. When an input FCW is received and an output FCW is responsively provided based on (i) an interpolation between two reference output FCWs of the set of reference output FCWs and (ii) the respective sensitivity characteristics of the at least two capacitor banks of the oscillator. The output FCW is then applied to the at least two capacitor banks of the oscillator.

摘要： Systems and methods for up-sampling a polar amplitude sample stream in a polar modulator are disclosed. In some embodiments, a process includes receiving, at a polar modulator, an in-phase sample stream and a quadrature sample stream which together characterize a data signal in an IQ plane. The process includes generating a polar amplitude sample stream and a polar phase sample stream. The process includes generating an up-sampled polar amplitude sample stream by (i) identifying an origin crossing of the data signal in the IQ plane, (ii) responsively adjusting an inversion trigger, (iii) selectively applying an inversion to the polar amplitude sample stream based on the inversion trigger, (iv) interpolating the selectively inverted polar amplitude sample stream, and (v) removing the inversion from the interpolated selectively inverted polar amplitude sample stream. The process includes modulating a carrier signal using the up-sampled polar amplitude stream and the polar phase sample stream.
