WebBPSK - binary phase shift keying, of which the present experiment is an extension. DPSK A disadvantage of BPSK is that the receiver requires a knowledge of the frequency and phase of the carrier of the incoming signal. As for BPSK, DPSK requires a local carrier for successful synchronous demodulation. But the phase of this carrier need not be ... WebIn this paper, tight and universal bounds are derived for the interchannel interference (ICI) of an OFDM signal resulting from Doppler spread. The universal bound depends only on the product of the maximum Doppler frequency and the OFDM symbol duration. The tight bound also depends on the variance of the Doppler spectrum.
