Hello All, My name is Charles and I'm a senior at California State University Northridge. The team I am with is currently working on implementing a digital communications scheme between a flying object and a ground based station.
I am having issues with the Demodulation block of the DPSK (in DBPSK mode). The setup is, I read a binary file and send that directly into the DPSK Modulator. I then immediately Demodulate this signal in the GRC window and put it into a file. This process is not the inverse of itself. The output file is unintelligle to me with a text editor and with a hex editor. My question is, if I were to open and read a binary file of only alternating 1s and 0s into the DPSK modulator then immediately feed that back into the demodulator, what format is the demodulator putting byte data back out? Is it padding the information with 0s? Any insight into "how" the demodulation block submits the byte data to the subsequent connecting block would be greatly appreciated.
