This example illustrates two different methods of creating an end-to-end QPSK system.

The first method, in the system diagram "QPSK TX RX BER", makes use of the QPSK_TX and General I/Q receiver blocks.

The second method, in the system diagram "QPSK Quadrature", constructs an equivalent system using basic blocks.

The ALIGN block in "QPSK Quadrature" is used to compensate for the group delay of the pulse shape filter. The receiver blocks such as RCVR and QPSK_RX automatically handle the group delay compensation.
