Digital Phase Modulation: BPSK, QPSK, DQPSK Radio Frequency

WebHowever there is a caveat. We have inserted a CP which means we are transmitting more energy than simple BPSK. To be exact we are transmitting 1.25 (160/128) times more energy. This means that if this excess energy is accounted for the performance of BPSK-OFDM would be 1dB (10*log10(1.25)) worse than simple BPSK in Rayleigh flat fading … WebWe propose frequency-domain OCDM employing BPSK in addition to multi-level ASK based on electrical-domain spatial code spreading.
