Delay detection demodulation system |
摘要 |
Disclosed is a delay detection demodulation system which has: a plurality of receiving systems; a plurality of instantaneous phase detecting circuits for detecting an instantaneous phase from the output of each of the plurality of receiving systems; a plurality of phase difference operating circuits for determining a phase difference in one symbol section from the output of each of the plurality of instantaneous phase detecting circuits; a combining circuit for combining the outputs of the plurality of operating circuits; a delay detection circuit for conducting error diffusion type delay detection after the combining of the combining circuit; and a demodulation logical circuit for conducting demodulation logical operation.
