Demodulation

In this simulation, the Viterbi Decoder block is set to accept unquantized inputs. The BPSK Demodulator block produces hard decisions, so it cannot be used for demodulation in this model. Instead, the simulation passes the channel output through a Simulink Complex to Real-Imag block that extracts the real part of the complex samples.
