Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a modulation system which reduces mutual interferences and produces orthogonal pseudo-noise(PN) sequences so as to overcome fading.

SOLUTION: A means (604) which generates a 1st orthogonal sequence signal that corresponds to one selected sequence from among plural orthogonal binary sequences receives an input signal and converts a sequential part of the input signal into one orthogonal binary sequence selected from among plural orthogonal binary sequences respectively according to the value of each input signal part a means which generates a PN signal generates a PN signal corresponding to a PN binary sequence that is defined beforehand and connecting means (610 and 612) connect the 1st orthogonal sequence signal and the PN signal and supply a result signal.
