  • Finite impulse response filter with parallel input
    Patent number: 9098435
    Abstract: A filter and method for finite impulse response filtering an input signal is described. In one embodiment, the filter includes an input circuit configured to receive input samples in parallel, where the parallel input samples correspond to sequential samples of the input signal. In another embodiment, the filter includes a coefficient memory configured to store filter response coefficients and output a subset of those coefficients corresponding to a selected decimation factor.

  • Parallel infinite impulse response filter
    Patent number: 8725785
    Abstract: A technique for performing parallel-input parallel-output infinite impulse response (IIR) filtering uses two parallel-input-parallel-output finite impulse response (FIR) filters. One FIR filter is used as a feed-forward filter and one FIR filter is used as a feed-back filter. The feed-back filter is coupled to delays and summers to allow the filter operations to be performed in parallel.

  • Efficient digital upconverter
    Patent number: 8295388
    Abstract: Techniques for efficient upconversion can process complex input data, such as for example data in an inphase and quadrature form. Half sample interpolation filtering and delay can be performed, and the results can be combined in a quarter-rate upconverter. The quarter rate upconversion can allow one of the half-sample interpolating filtering and the delay to be performed on one of either the inphase and quadrature samples.

  • Low-density parity check decoding using combined check node and variable node
    Patent number: 8266493
    Abstract: A technique for decoding low-density parity check codes includes performing a combined check node and variable node calculation. Decoding is initialized using channel likelihood values estimated from a received physical signal. The decoding iteratively updates the variable nodes. Performing a combined check node and variable node calculation can enable reduced memory usage and faster convergence for the decoder.

  • Encoder for low-density parity check codes
    Patent number: 8095859
    Abstract: Encoding of a low-density parity check code uses a block-circulant encoding matrix built from circulant matrices. Encoding can include partitioning data into a plurality of data segments. The data segments are each circularly rotated. A plurality of XOR summations are formed for each rotation of the data segments to produce output symbols. The XOR summations use data from the data segments defined by the circulant matrices. Output symbols are produced in parallel for each rotation of the data segments.
