Method of coding signal for digital optical communication having spectrum which attains zero level at prescribed frequency
摘要:
A method of coding a signal for digital optical communication using a symbol formed of N slots [s1, s2, s3, . . . , sN], wherein si is either 0 or 1 where i is an integer and 1≦i≦N is provided. The method includes the steps of determining a plurality of symbols which satisfy the following expression, wherein k is an arbitrary positive integer, and p1, q1, p2, q2, . . . , pk and qk are integers which satisfy 1≦p1
