Doing modulo arithmetic vis-a-vis the radio communication system, the receiver, and the recovery methodological null desire signal

摘要

PROBLEM TO BE SOLVED: To improve a BER (Bit Error Rate) when a receiver receives a signal created by a transmitter applying a modulo operation making speed up of a communication speed or stability of communication quality as an object.SOLUTION: The radio communication system is provided with at least the receiver which receives the signal created by the modulo operation, acquires transmission route information relating to a transmission route status between the transmitter and the receiver from the received signal, acquires operation information relating to the modulo operation, and has a demodulator which outputs discrimination result of the signal based on the transmission route information and the operation information.
