| 1. A transmitter apparatus comprising:
an input receiving section that receives inputs of multiple synchronized signals r1, . . . , rN;
an asynchronizing section that delays the multiple input received synchronized signals r1, . . . , rN by times t1, . . . , tN,respectively,to output multiple asynchronized signals v1, . . . , vN;
a modulating section that modulates the output multiple asynchronized signals v1, . . . , vN to output modulated signals w1, . . . , wL(1≤L≤N); and
a transmitting section that transmits the output modulated signals w1, . . . , wL, and
wherein the delay times t1, . . . , tN are respectively proportional to values u1, . . .uN which are computed from a prestored interger value a, a predetermned nonlinear transformation f (•) over a finite, field and
the equations:
u1 =a;
u1+1=f(u1)(1≤j≤N).
