Abstract
An input receiving section 102 of a transmitter apparatus 101 receives inputs of multiple synchronized signals r1, . . . , rN, an asynchronizing section 103 outputs multiple asynchronized signals v1, . . . , vN that are obtained by delaying the multiple synchronized signals r1, . . . , rN by time t1, . . . , tN, a modulating section 104 modulates the multiple output asynchronized signals v1, . . . , vN to output modulated signal w1, . . . wL (1≦L≦N), a transmitting section 105 transmits the output modulated signal w1, . . . wL, and the delay time t1, . . . , tN is shorter than a reciprocal number of a minimum value of clock rates of the multiple input received synchronized signals r1, . . . , rN, and is desirably proportional to one generated by a chaos random number in particular.
