Re: [Discuss-gnuradio] Data loss during transmission (OFDM .bmp file)

Hi Ben, I am trying to transmit an image using USRP Tx/RX by implementing OFDM in GNU Radio. I am losing one offset of 96 bytes. I am suspecting there is problem with my synchronization which is not detecting that offset (packet_len = 96 bytes) or probably discarding it. I also tried inserting padd

Hey Simran - All of this is to say that your communications system design does not appear to be robust to the impairments and complexities of wireless channels, some of which Marcus mentioned. Can you share what your specific goal is or why you're undertaking this work? Depending on what you are t

Well, noise happens, and synchronization isn't instantaneous. Things that aren't detected can't be received, and bit errors that the FEC can't correct are bit errors in the received data. That's the beauty and the curse of wireless communications. Best regards, Marcus On Sat, 2019-05-04 at 20:26
