The peak-shoulder difference might be too large to be captured with the USRP, as the ADC has 12 bit and DAB signals have a large crest factor. - Implement cases for different oversampling for FFT bin choice. - Continuously observe DAB signal in frequency domain and make sure the power stays the same. At the moment only the power in the time domain is kept the same. + - At the moment we assume that the USRP RX gain has to be larger than 30dB and the received signal should have a median absolute value of 0.05 in order to have a hight quality quantization. Do measurements to support or improve this heuristic. |
