Polyphase Resampling (rational resampling) #194

Open xerpi opened 2 weeks ago

xerpi commented 2 weeks ago

Since CMSIS-DSP already provides functions for FIR decimation and FIR interpolation, it would be beneficial to include efficient rational resampling functionality using the polyphase resampling algorithm.

For reference, see SciPy's scipy.signal.resample_poly, GNU Radio's Rational Resampler, FutureSDR's PolyphaseResamplingFirKernel, and SampleRateConverter.

Good suggestion. Tagged as "enhancement".
