An apparatus for generating orthogonal sequences is disclosed which includes an M-sequence generator for providing a signal of M-sequence of which the component takes 0 or 1 and the period is N, and substitution means connected to the output of the M-sequence generator for substituting the component of the M-sequence. The substitution means substitute the component with A0ej phi 0 when the value of the component is 0 and with A1ej phi 1 when it is 1, where each of A0 and A1 is a positive real number, and the substitution is performed so that a trigonometric function f1( phi 1- phi 0) having a phase of ( phi 1- phi 0) is a ratio of two functions f2(A1/A0) which is a quadratic function of A1/A0 with a coefficient of a linear function of N and f3(A1/A0) which is a linear function of A1/A0 with a coefficient of a linear function of N, whereby the orthogonal sequence is generated from the substitution means. |
