We can see in the picture below that everything seems to work perfectly : when I compare the input bit stream to the output bit stream the bits are synchronized. However when I open the file at the output of the flowgraph I'm unable to get the bit frame that I had at the input.

WebI made a DQPSK modulator and demodulator using just GNURADIO companion. (screenshots provided) Gave a vector source with bits 0,1,0,1 and repeat on, on the input of PSK modulator. I also used an error rate block to calculate bit error rate. (Vector source is on ref of error rate block and DQPSK demodulator output is on input).
