Title:
COMMUNICATION EQUIPMENT USING CARRIER MODULATED BY RANDOM NUMBER CODE
Document Type and Number:
Japanese Patent JP2002027000
Kind Code:
A
Abstract:
To provide a communication equipment with excellent confidentiality.
The communication equipment is provided with a random number code generator employing a noise, or a radiant ray, or a numeric expression at its receiver side. The receiver side transmits a carrier modulated by the random number code, a transmitter side uses a modulation code receiver 8 to receive the carrier sent from the receiver side, uses data to modulate this carrier and transmits the modulated data, and the receiver side applies addition/ subtraction or multiplication/division of the carrier sent to the transmitter side from the received modulation wave to demodulate the data.
