Hi,
I am working with gnuradio’s ofdm transmitter using benchmark_tx.py
platform. The problem I’ve encountered is the ofdm spectrum has a strong
peak at the center carrier frequency and this peak is almost 30 dB
higher than ofdm spectrum itself, it seems to me like a DC problem or I
don’t know… Maybe anyone with more expertise can advice something, how
to avoid or remove this problem?
Many thanks!
