摘要

PROBLEM TO BE SOLVED: To provide a phase demodulation method for minimizing a phase error caused by noise propagation in a phase space in a demodulation process of a phase-modulated communication signal.;SOLUTION: In the phase demodulation method for minimizing the phase error of the communication signal, the phase-modulated communication signal is demodulated through predetermined times of sampling utilizing a predetermined digital phase demodulation algorithm represented by a formula 1 (wherein k indicates the number of times of sampling and C_k indicates a complex constant number). Single sampling for minimizing the phase error is added to the digital phase demodulation algorithm, thereby demodulating the phase-modulated communication signal.;COPYRIGHT: (C)2004,JPO
