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 square like OFDM signal but on the other hand in spectrum analyser it shows only one peak sine wav signal not OFDM. I tried to play with the setiings but couldnot get the desired ofdm signal output. This is just tranmitter setup and i attched with spectrum anlyzer but i dinot get OFDM signal . iam only getting simple sine wave in the spectrum analyser. I tried with simple random sourse block and then DQPSK modulator and Usrp sink then it worked it shows sine wave signal in out put at spectrum analyser.Please any body know how to fix this problem or any solution ??? For reciever part i will use the same block in reverse order with ofdm demodulator.. All suggestions are appriciated. Looking forward to it...
Thanks in advance.. waq. -- View this message in context: http://old.nabble.com/OFDM-Transmiter-and-receiver-by-using-USRP1-tp32662445p32662445.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
