Patent ID: 7577182

Claim:
A transmitter apparatus comprising: an input receiving section that receives inputs of multiple synchronized signals r 1 , . . . , r N ; an asynchronizing section that delays the multiple input received synchronized signals r 1 , . . . , r N by times t 1 , . . . , t N ,respectively,to output multiple asynchronized signals v 1 , . . . , v N ; a modulating section that modulates the output multiple asynchronized signals v 1 , . . . , v N to output modulated signals w 1 , . . . , w L (1≦L≦N); and a transmitting section that transmits the output modulated signals w 1 , . . . , w L , and wherein the delay times t 1 , . . . , t N are respectively proportional to values u 1 , . . .u N which are computed from a prestored interger value a, a predetermned nonlinear transformation f (•) over a finite, field and the equations: u 1 =a; u 1+1 =f(u 1 )(1≦j≦N).
