Hi. I’m new to GNU Radio but have experience with basic DSP (using
MATLAB for instance). Which blocks can I use to do these simple
tasks:
-
Convolution with an arbitrary (constant) wave in the time domain?
Example: I provide the wave as a fixed series of constants, I’d like
to convolute with it.
-
The same thing in the frequency domain?

The fir_filter_XXX does time-domain convolution. You’d pass it a
decimation of 1 and the taps would be the signal you want to convolve
against.
The fft_filter_XXX does fast convolution in the frequency domain.
