Re: [Discuss-gnuradio] Maximum possible transmission rate through the benchmark code

Alex, Thanks for the email. I think that the high bitrate occuring at OFDM and modulations except gmsk come mostly from peak to average power ratio issues. GMSK works best for everyone, I guess. I am just surprised to see how the uhd_fft.py is measuring the signal strength in the 20 MHz band. I t

Nazmul, Seems you are doing the similar experiment with me. In my test for both OFDM and narrowband, the 20MHz bandwidth is too wide to be supported by my computer. For OFDM, I am using the tunnel.py to test the ping, unfortunately, most of the time, the ARP query fails. So I have to use the sta

Hello, I am running the benchmark_tx and benchmark_rx codes of the narrowband and ofdm folder (gr-digital/examples) between two USRP2's. I have several questions regarding the maximum possible transmission rate in these two codes. I am listing the questions and my experiment details below: USRP2
