Error with Text file modulation and demodulation for BPSK

[Ratnakar V Maller]

Hi All,

 

I am a GNU Radio enthusiast and am trying to modulate a text file and get back the same as output after demodulation. But, I am facing an issue due to which ambiguous data is being generated.

 

BPSK demodulation only returns binary data, and not the original text file with or without data loss.

 

I will be attaching the flowgraphs below. Please instruct on what needs to be done and what corrections are needed.

 

I also tried doing Manchester coding, upconversion and doppler shift in the order specified but it is not working with a normal signal source. Please help.

 

All the gnu radio files will be attached below.

 

Thanks and regards,

Ratnakar
