I've tried to use examples from Textbook to process my own signal, after I tried full code example and provided file, I'm still getting wrong results as I can assume...

First, thanks for the great book! It helps me a lot to get started in SDR. In the USRP chapter, you said that the UHD only supports `fc64` and `fc32`...

eg adapting https://github.com/radio-satellites/python-hrpt and it would use a recording of HRPT off IQEngine

clarify what an unmodulated carrier looks like, and remove the cos and arrow.

At the end of the chapter add a full python simulation showing reading some input data (eg an ASCII message), generate QPSK, simulate a channel, receive/demod/decode the ASCII, and compute...

Hi Marc! Many thanks for the great work! PySDR was the ideal introduction to the world of sdr for me! What I'm still missing is a routine that searches for...

Hi, I wrote a more convenient wrapper for bladerf too (allows you to control all device functions, except for asynchronous calls with a timestamp) It also allow to work with...

Coarse Frequency Synchronization without knowing modulation order.

3

Hey, I tried the Coarse Frequency Synchronization on the QPSK signal, it is working fine. I modified as: psd = np.fft.fftshift(np.abs(np.fft.fft(samples ** 4))) samples = samples * np.exp(-1j*2*np.pi*max_freq*t/4.0) But the...
