    摘要: 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.

    摘要: A method and system is disclosed for demodulating multiple waveforms, with different modulation formats, in the same hardware by providing a software-configurable demodulator that configures itself in response to varying input waveform types. The system reconfigures its logic to accommodate the format of the signals being received and further allows for reconfiguration of demodulator functional block interfaces to remove downtime during multiple waveform processing.
