i use the following command to capture some samples of noise
uhd_rx_cfile -a serial=4759a751 -N 100000 -f 2.48G --samp-rate=2M noise.dat
then using matlab i read the samples
y=read_complex_binary ('noise.dat');
and i do plotfft
plotfft(y,2000000)
the plot shows a peak near the center. I don't know why. what could i do on the samples y so that the peak not appeared?
i attach the figure of plotfft
