Abstract

A radio communication system including a transmitter for sending a part of transmission signals at different time in a redundant manner and a receiver for receiving the signal sent from the transmitter, wherein the receiver compares a part of transmission signals received at different time with each other, and estimates a propagation path between the transmitter in accordance with the comparison result.
