OUTPUT DEVICE, TRANSMISSION DEVICE, RECEPTION DEVICE AND COMMUNICATION SYSTEM FOR PSEUDO RANDOM NOISE SYSTEM, OUTPUT METHOD, TRANSMISSION METHOD AND RECEPTION METHOD FOR PSEUDO RANDOM NOISE SYSTEM AND INFORMATION RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an output device, a transmission device, a reception device and the communication system for a PN system, an output method, a transmission method and a reception method for the PN system and an information recording medium. ;SOLUTION: The output device 101 of a PN system outputs the PN system of length N (1N), which is generated by a Chebyshev's polynomial T (a, cos)=cos(a) on an integer a (2a). A reception part 102 receives the S (1S) pieces of system initial values X1, X2,... Xs of a real number which are each above '-1' and below '1' and the degree p1, p2,..., ps of S-pieces of an integer which is not less than '2'. A calculation part 103 calculates the pseudo random noise system z[1], z[2],..., and z[N] of length N by the system initial value, the degree and a recurrence formula xj[1]=Xj; xj[m+1]=T(pj, xj[m]); z[n]=IIj1ST((pj, xj[n]) on integers j(1jS), m(1mN-1) and n(1nN). An output part 104 outputs the PN system. The PN system is used for direct spread spectrum communication as a spread code.;COPYRIGHT: (C)2001,JPO
