Abstract: A method is for estimating drift between a first clock used in a digital transmission processing of a first Ultra Wide Band (UWB) pulse train signal and a second clock used in a digital reception processing of a second UWB pulse train signal resulting from a transmission of the first UWB pulse train signal. The method may include sampling the second UWB pulse train signal, and calculating trellis information representative of a trellis having reference paths respectively associated to different reference values of the drift and including sample transitions of a sampled third signal from the sampled second UWB pulse train signal. The method may further include processing the sampled third signal along the trellis for obtaining a path metric for each processed reference path, and selecting the processed reference path having a greatest path metric, the drift being the reference value associated to the selected processed reference path.

Abstract: A transmission band of an analog signal including successive symbols to be transmitted is notched, where each symbol includes sub-carriers to be modulated. In particular, in each symbol the sub-carriers corresponding to a part of the transmission band to be notched are suppressed. In addition, in each symbol a chosen part of the remaining sub-carriers to be modulated is also suppressed.

Abstract: A method for converting a sampling frequency of a digital signal sampled at a first sampling frequency includes receiving digital signal input samples, and forming output samples corresponding to a second sampling frequency based on the digital signal input samples and an interpolation filter. The first sampling frequency may be larger than the second sampling frequency. The method may further include delivering the output samples. Forming output samples includes, for each of the digital signal input samples, updating current values of N successive output samples with N contributions. The N contributions may be respectively calculated based on a value of a current input sample of the digital input samples weighted by values of N filter coefficients associated with the current input sample, N being fixed and identical for all the digital signal input samples regardless of a value of the conversion ratio between the first and second sampling frequencies.

Abstract: A receiver for high-speed data communications, which receives a differential signal through a pair of signal lines. The receiver includes a common-mode choke, which has first and second signal windings, which are respectively coupled in series to the pair of signal lines so as to attenuate common-mode interference in the differential signal. The choke also has a sampling winding, which is inductively coupled to the signal windings so as to generate a sampled signal responsive to current flowing in the signal windings. Signal processing circuitry is coupled to receive the sampled signal from the sampling winding and to receive the differential signal from the signal windings and to process the differential signal responsive to the sampled signal.
