Hello,
This is an OFDM packet consisting of 6 symbols: the
default sync word 1&2, SIG field and three data
symbols. The data symbols are QPSK modulated and the
sync words are BPSK.
Is there any way that I could reduce or eliminate
these large spikes that even with a moderate baseband
scaling still go considerably above a magnitude of 1?
I have tried to use different data, and a different
number of packet data symbols, but to no avail. I am
definitely able to reduce the overall baseband scaling
and get those spikes within range, but this is not
desirable as I am trying to maximize transmit power.
The usage of the USRP-2974 and sampling rate is
immaterial; this happens using a variety of different
radios (should not matter as this is a GNU radio
"issue") and sampling rates.
If anyone has seen this before or may have any
advice, please let me know.
