摘要
An M-ary digital pulse period modulation and demodulation method for use in an optical communication system, which relates to an M-ary digital pulse period modulation and demodulation method. It is intended to improve the data transmission rate of an optical communication system. The modulation method is that: the M-ary system data of an optical communication system are modulated into a binary pulse using an MDPCM method; and the modulation method is realized by changing the period of the binary pulse corresponding to each code element in the M-ary system data. The demodulation method is that: demodulated data are obtained from the modulated binary pulse according to a demodulation formula. The present invention is applicable to an optical communication system.
