Abstract: A signal transmission system includes an equalization filter configured to filter an input signal based at least in part on a feedback signal, a slicer configured to generate data based on the filtered input signal at a plurality of different phases, a synchronizer configured to compute a phase delay between the input signal at each of the different phases and the data, and a pattern generator configured to generate the feedback signal at a phase adjusted by the phase delay.

Abstract: A one-time write, read-only memory for storing trimming parameters includes an address pointer table, a fixed packet portion, and a flexible packet portion. The fixed packet portion includes one or more fixed packets, each fixed packet including trimming parameters for a component identified for trimming during a design phase. The flexible packet portion includes one or more flexible packets of different types. Each flexible packet includes trimming parameters for a component identified for trimming after the design phase. One packet type includes a length section and a number of fields equal to a value stored in the length section. Each field includes an address, a trimming parameter, and a mask. Another packet type includes trimming parameters associated with operands in operating instructions for a microcontroller, where the operands include an address and a mask.

Abstract: A method for adapting a continuous time equalizer (CTE) includes determining a gain of a discrete time equalizer (DTE) and determining whether the gain has increased or decreased by more than the threshold amount. Responsive to determining that the gain has increased or decreased by more than the threshold amount, the method includes sequentially configuring the CTE for multiple CTE settings such that gain of the CTE is caused to increase or decrease in a same direction with the change in gain of the DTE. The method also includes determining a separate figure of merit (FOM) for each of the multiple CTE settings and selecting a new CTE setting from the multiple CTE settings based on the FOM for each of the multiple CTE settings.

Abstract: A method for frequency domain to time domain conversion includes receiving a set of frequency-domain samples. Based on the set of frequency-domain samples, a first sample subset comprising a predetermined fraction of the number of samples of the set of frequency-domain samples and a second sample subset comprising the predetermined fraction of the number of samples of the set of frequency-domain samples are generated. A linear phase rotation is applied to the first sample subset and the second sample subset to produce a phase rotated first sample subset and a phase rotated second sample subset. The phase rotated first sample set is post-processed to generate a first set of time-domain samples. The phase rotated second sample set is post-processed to generate a second set of time-domain samples. The first set of time-domain samples and the second set of time-domain samples are reordered to produce an output set of time-domain samples.

Abstract: Enhancing search capacity of Global Navigation Satellite System (GNSS) receivers. A method for searching satellite signals in a receiver includes performing a plurality of searches sequentially. The method also includes storing a result from each search of the plurality of searches in a consecutive section of a memory. Further, the method includes detecting free sections in the memory. The method also includes concatenating the free sections in the memory to yield a concatenated free section. Moreover, the method includes allocating the concatenated free section for performing an additional search.

Abstract: A receiver circuit comprising an equalizer and a method of correcting offset in the equalizer. In an example, the equalizer includes a plurality of delay stages for sampling and storing a sequence input samples, and a plurality of coefficient gain stages, each coupled to a corresponding delay stage to apply a gain corresponding to a coefficient value. The outputs of the coefficient gain stages are summed to produce a weighted sum for quantization by a slicer. Offset correction circuitry is provided, including memory storing a look-up table (LUT) for each coefficient gain stage, each storing offset correction values corresponding to the available coefficient values for the coefficient gain stage. Addressing circuitry retrieves the offset correction values for the coefficient values currently selected for each gain stage, and applies an offset correction corresponding to the sum of the retrieved offset correction values.
