Hello, Adding some more information to the previous mail, that I want to use only receiver part from GNU radio and SDR and my transmitter is different from which I am transmitting modulated signal and received and demodulated using GNU radio. so, when I am doing simulation( using back to back blocks of constellation modulator with the demod blocks) I am receiving the 1100 and 1010 data same as transmitted. but , when I am using the receive only blocks and use external transmitter, then also received data changes.
I don't understand , where is the main problem. Kindly help.

[ https://www.rapidtables.com/convert/number/ascii-to-binary.html | https://www.rapidtables.com/convert/number/ascii-to-binary.html ] But I am facing an issue, while I am transmitting repetitive pattern such as 1100, 1010 , the data stored in the file after mod-demod is almost similar( only some initial bits are changed) . Please check the screenshot attached. But when I am transmitting some random pattern instead of repetitive using file source, I am not receiving the same pattern, while I am converting the stored ASCII to binary using converter. I have sent the GRC file in previous mail. Kindly let me know, where is the problem? Waiting for your positive response.
