hi Marcus, I am attaching the screen shots and also block diagram of transmitter.. right now i am just trying to look for transmission of OFDM signal via usrp1. As i mentioned earlier in the fft scope plot in gnu radio i see the typical ofdm signal but on the other hand in usrp sink on the

Hello Marcus thanks for your reply.. Well the problem is there is not much documentation available on internet on usurp .. Also I am quite new to gnu radio and usrp1 ... I tried to play with interpolation and decimation settings but didnot get the desired ofdm signal .. I am not sure what else I

Hello all, I am trying to transmitt and recieve OFDM signal Via USRP1 board. I made basic simulation in GNU radio a signal source block and then interleave and then OFDM modulator and then channel model block then usrp1 sink and fft sink to see the output..In FFT sink at the end it shows proper

Hi Marcus, As i mentioned the flow graph signal blocks i have used in gnu radio companion from that i am getting this out put on FFT sink in GNU radio companion simulation flowgraph which is similar like this and i have used RF cable to connect from USRP1 TX board to the spectrum analyser
