Abstract:
A method of finding the best possible equalization of an electric input signal (S) which was derived from an optical signal (L) transmitted over an optical fiber and which is distorted due to interference in the optical signal, said method comprising the steps of:determining the quality (Q) of the distorted output signal (S.sub.1, . . . , S.sub.i, . . . , S.sub.n);determining at least one set (i) of equalization parameters (E.sub.i,1, . . . , E.sub.i,m) as a function of at least two arbitrarily assumed interference parameters (P.sub.1, . . . , P.sub.j) which characterize the interference from which the distortion results, with the number (j) of interference parameters (P.sub.1, . . . , P.sub.j) being less than the number (m) of equalization parameters (E.sub.i,1, . . . , E.sub.i,m) of the at least one set (I); andthen varying the interference parameters (P.sub.1, . . . , P.sub.j), and thus the equalization parameters (E.sub.i,1, . . . , E.sub.i,m) of the at least one set (i) until the quality (Q) of the equalized output signal (S.sub.1, . . . , S.sub.i, . . . , S.sub.n) is optimized.
