6) Data decoder: Performs phase ambiguity resolution and demodulation. Also, the data decoder compares the regenerated message with the transmitted one and calculates the BER. Scopes This component provides optional visualization to plot: A spectrum scope depicting the received signal before and after...
the phase of the recovered carrier is in error, then demodulation The seed value is fully programmable for both configurations. The seed value is reset prior to each burst and is used to calcu- late the randomizer bit, which is combined in an exclusive XOR with the first bit of data from...
7) Data decoder: Performs phase ambiguity resolution and demodulation. Also, the data decoder compares the regenerated message with the transmitted one and calculates the BER. For more information about the system components, refer to the QPSK Receiver with ADALM-PLUTO Radio example using...
3) QPSKReceiver.m: models the receiver, including components for phase recovery, timing recovery, decoding, demodulation, etc. 4) QPSKScopes.m: optionally visualizes the signal using time scopes, frequency scopes, and constellation diagrams. Each component is modeled using a System object. To see...

A data recovery algorithm was proposed for DLI-based DP-QPSK demodulation. The simulation results demonstrated that the algorithm could accurately recover the raw data from the transmitter. Moreover, decreasing the differential delay of the DLI could effectively increase the chromatic dispersion tolerance...
