Good morning,
I’m evaluating the difference between a single carrier modulation and a
multi carrier modulation, so I decided to implement a TX-RX system in
GNURadio companion working with USRP N210.
I’d like to plot a graph of the packet loss in these two modulation,
placing the antennas at different distances, but I’m not able to know
the transmitted packets and the received ones, can you help me?
My parameters are:
DQPSK Transmitter:
Audio Source → Packet encoder → DPSK MOD-> UHD:USRP SINK
OFDM Transmitter
Audio Source ->Packet encoder ->OFDM MOD-> UHD:USRP SINK
Using a OFDM simulation, I tried to find the TX and RX packets as the
way of the attached file.
Moreover, placing the same blocks at this link
http://gnuradio.org/redmine/attachments/download/399/screenshot-grc-bersimu.png
in order to evaluating the BER in a TRANSCEIVER SIMULATION with a vocal
source, it doesn’t works.
How can I find the BER in a simulation using DQPSK and in another one
using OFDM?
Thank you very much!!
