* When order=2: used for BPSK where the real part of the output signal is the baseband BPSK signal and the imaginary part is the error signal. | * When order=2: used for BPSK where the real part of the output signal is the baseband BPSK signal and the imaginary part is the error signal. | ||
* When order=4: can be used for QPSK where both I and Q (real and imaginary) are outputted. | * When order=4: can be used for QPSK where both I and Q (real and imaginary) are outputted. |
