Almost a month ago, I started working on a digital communications project that includes GNUradio. And I'm trying hard to overcome some mistakes or inconsistencies. I'm meeting at GNUradio. I desperately need some kind of expert help. I made a DQPSK modulator and demodulator using only the GNURADIO companion. (Screenshots provided)
Give a vector source with bits 0,1,0,1 and repeat, at the input, a PSK modulator. I also used an error block to calculate the error rate in bits. (The vector source is included in the error blocking unit, and the output of the DQPSK demodulator is at the input). I connected the wx gui area to the error rate block and the constellation receiver to the PSK module. Now almost everything that appears on objects is completely wrong.
