Path in the library: |
Description
The QPSK Demodulator Baseband block demodulates a signal that has been modulated using the quadrature phase manipulation method. The input is a representation of the modulated signal in the modulating frequency band.
The input must be a complex signal. This block accepts the input signal as a scalar or column vector.
