Hi all, I tried to develop an OFDM transmitter and Recevier Using the OFDM Modulator and Demodulator blocks available in GnuRadio.v3.4.2 Since I haven't received my USRP, I decided to test it using the TCP.
My PC Configuration: Intel Core2Duo E8500 @3.16GHz 4GB RAM, Fedora 16 , 64Bit. The OFDM configuration: BPSK,128FFT, 96Tones, sampling freq=2Mhz The problem that I face is that the transmitted file gets corrupted only for certain file sizes. I have attached a test result(pdf) of transmission of files with different sizes. I'm unable to figure out the issue. The attached images shows the flowgraphs of Transmitter and Reciever. I have also attached the python files.
