INFORMATION TRANSMISSION RECEPTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an information transmission reception method in which a task of realizing a communication channel is much simplified by increasing a compression coefficient by several orders of magnitude in the method using a UHF as a carrier of an information signal. SOLUTION: A carrier generator 1 generates a carrier with an ultrawide frequency band fc at a UHF band. A 2-branch device 2 divides a carrier outputted from the carrier generator 1 into two signals. A delay circuit 3-1 delays one of the signals outputted from the 2-branch device 2 by a time T. A multiplier 4-1 multiplies the information signal outputted from an information signal generator 5 with a signal from the delay circuit 3-1 to provide an output of a transmission information signal. The transmission information signal is synthesized with a support signal being a signal outputted from a 2nd output terminal of the 2-branch device 2 at an adder/amplifier 6, which produces the transmission signal and amplifies the transmission signal at a designated amplification factor to attain a desired output.
