Description Usage Arguments Value See Also Examples
Receives a vector of complex values, r, corresponding to a QPSK modulated signal transmitted through a communications channel (e.g., signal plus noise). The received signal, r, is mapped to its in-phase (real part) and quadrature parts (imaginary part) and demodulated, such that two binary bits are output for each value of r. If the in-phase part is > 0 then the corresponding output bit value is 1, otherwise 0. Similarly, if the quadrature part (imaginary) > 0 then the corresponding bit value is 1, otherwise 0.
