Title: Direct spread frequency communication equipment
Inventor: HIROO AKIRA
IPC: H04B1/707
Filed: 1988-08-24
Abstract: PURPOSE:To execute a communication with a high secrecy by obtaining a random number used for a spread frequency from a natural random number. CONSTITUTION:Instead of a pseudo-random number(PN) generator, natural random number generators (natural random number memories) 15 and 17 to generate the natural random number are used. Namely, by providing the natural random number memories 15 and 17 to generate the same natural random number at transmitting and receiving both sides, a signal spread at the transmitting side can be inversely spread, and simultaneously, since the generated random number is the natural random number, a random number series is not imbalanced to a specific pattern, and a spread code is made hard to find out by a tapping person. Thus, a direct spread frequency communication equipment can be obtained in which communication contents are hardly decoded even when they are tapped by the third party.
