    Understanding Phase-offset in 4-QAM/QPSK

    I stambled on a Matlab solution to calculate the phase by which symbols in the Rx of a 4-QAM have been shifted and therefore do the phase correction. The solution is only custome to Tx'ng and Rx'ng 432 bits, which therefore takes 2bits per symbol. The thing is, i don't understand well how they...
