Dear
When capturing the samples with the following configuration, these amplitudes appear at the edges, what is the reason for this?
dev = limeSDR(); dev.rx0.frequency = 863100000; dev.rx0.samplerate = 4000000; dev.rx0.bandwidth = 2000000; dev.rx0.gain = 0; dev.rx0.antenna = 3; dev.rx0.enable; dev.rx0.calibrate; dev.start(); [IQ_samples, ~ , actual_count] = dev.receive(10000000,0);
Thank you
It is FFT properties: results are repeated after Fs/2 (sample rate). What you see at the edges are central spike (received local oscillator leakage). If you increase sample rate or decrease badwidth you will lose spikes.
@yt7pwr Thanks for your answer. I was reviewing the code of the libraries and I eliminated the spikes of the borders with the oversampling options.
