Abstract: The present subject matter discloses a system and a method for processing of channel coefficients of networks. In one embodiment, the method includes ascertaining at least one probable synchronization position of a received sequence and projecting, by oblique projection, at least one given noise basis vector spanning a given noise space onto the null space, so as to determine a channel impulse response at the at least one probable synchronization position. Based on a criterion related to the channel impulse response, a synchronization point for the received sequence is identified from the at least one probable synchronization position. The method also includes determining the noise contribution at the synchronization point and determining the noise coefficient of the at least one given noise basis vector based on the noise contribution so as to recover a signal substantially similar to the originally transmitted signal.

Abstract: The invention provides a method for controlling writing of data to a data storage card having a device controller and a storage medium. Particularly, the device controller receives a meta data synchronization disable command and in response, enters a first mode. In the first mode, the device controller does not synchronize meta data related to a data write request to write the data to the storage medium, leaving corresponding unsynchronized meta data. The device controller receives a data write request to write the data, and in response, effects the data write request such that the data is written to the storage medium. However, the meta data related to the data write request is not synchronized to the storage medium. Other aspects provide a corresponding device controller and software/firmware.

Abstract: A method for configuring an electronic device having an equalizer suited for processing a numeric audio signal according to an objective equalization improves the equalization of the numeric audio signal. The equalizer has a transfer function that implements a set of band-pass filters having a constant band-pass and a configurable weight in the transfer function. The method provides a set of objective gains representing the objective equalization, with each objective gain corresponding to a respective frequency. The method also determines values of the weights of the band-pass filters that minimize an error evaluated by comparing the set of objective gains to the transfer function. The set of band-pass filters includes at least one pair of band-pass filters having a common central frequency and distinct band-passes. The method also sets the weights of the band-pass filters to the determined values.

Abstract: There is described a method for compensating the phase and gain distortions of a transmitter analog front end affected by a leakage of a local oscillator. The method comprises generating a single complex tone signal in a digital front end, wherein the generation comprises compensating the signal gain and phase with gain and phase offsets. The method comprises feeding the compensated signal into the transmitter analog front end. The method comprises feeding a corresponding output signal of the transmitter analog front end into a nonlinear component, thereby generating an inter-modulation between the complex tone signal and at least one tone signal due to the local oscillator leakage. The method comprises feeding the output of the nonlinear component into a measurement receiver analog front end. The method comprises filtering the output of the measurement receiver analog front end with a band pass filter in order to isolate the inter-modulation, which is indicative of the distortions introduced by the transmitter analog front end. The method comprises measuring the power of the filtered signal. The method comprises updating the gain and phase offsets according to the measured power, by reducing said measured power. The disclosure also relates, in particular, to a digital front end, to an analog system, to a telecommunication device, to a computer program, and to a storage medium.
