Hello GR, I have multiple questions re the gr-specest toolbox:
1/ Is there any MTM estimator block for GRC 2/ Can anyone explain to me the figures in https://www.cgran.org/wiki/SpecEst related to Cyclostationarity-Based Modulation Classification. I am actually confused aren't they inverted (QPSK and BPSK) because it is in the QPSK that you find components on the Im. axis not in the BPSK. Any explanations is well appreciated. 3/ The README file talks about how to tune the update rate (sample_rate / block_len) however I tried to decrease it to almost 15, sample rate = 32k and block_len = 2048 and even I tried to have an FFT size 256, I always get the plot stuck and is hardly updating. No zoom is possible after I run the estimator. And after I run that, I cannot Pause nor close. I just have to kill the process. Am I missing something or some tuning.
