WebJan 11, 2013 · My next step is to do a phase-compensation for one of the USRPs so that both are aligned in the time-domain. I read from this document that for Phase-shifting, we need to use MRC algorithm or Periodic Calibration. Also I saw that a "Phase Shift" block has been used in that document which I guess was developed by the author who wrote … WebDigital demodulation requires bit-period synchronization; the receiver must be able to identify the boundaries between adjacent symbols. Binary-phase-shift-keying signals can be demodulated via multiplication followed by … boulanger ollioules 83

Webof phase with each other. The leading (channel 1) wave is the I or in-phase component of the complex signal and the lagging (channel 2) wave is the Q or quadrature component. … WebUsing a simple GNURadio flowgraph similar to the one that has been describe here, one could also use his favorite PSK31 software ( fldigi perhaps) for Doppler corrected transmission. The flowgraph would just sit between the PSK31 software and the audio output connected to the transceiver, and shift the audio frequency to correct for Doppler.
