Description

The Complex Phase Shift block applies a complex phase shift to a complex signal. This block independently processes each pair of corresponding elements.

Ports

Input

expand all

Input signal, specified as a scalar, column vector, or matrix.

Note

This block processes and outputs complex signals. Real values at the input port are type cast to complex values with +j0 complex components.

Data Types: double | single
Complex Number Support: Yes

Phase shift in radians, specified as a scalar, column vector, or matrix. If the phase shift is nonscalar, it must have the same dimension as the signal at port In.

Data Types: double

Output

expand all

Phase-shifted signal, returned as a complex-valued scalar, column vector, or matrix. This output is the same dimension and data type as the input signal.

Model Examples

Apply Complex Phase Shift to QPSK Signal

Apply Complex Phase Shift to QPSK Signal

The model applies QPSK modulation, and then applies a phase shift to a signal. Calculate the phase difference and plot the constellation of the signal before and after the phase shift.
