WebA demodulator is also employed for PI/2 BPSK. The modulated signal is received at the receiver side. This signal is compared with the threshold and the correct transmitted data is detected. 3. PI/4 QPSK: The π/4 QPSK modulation scheme is a modulation scheme that has combined a conventional QPSK modulation WebDemodulation of BPSK: Demodulation of a BPSK signal can be considered a two stage process: 1. Translation back to baseband, with recovery of the bandlimited message waveform 2. Regeneration from the bandlimited waveform back to the binary message bit stream. Translation back to baseband requires a local, synchronized carrier. Stage 1:
