Title:
COMMUNICATION SYSTEM AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/077753
Kind Code:
A1
Abstract:
A communication system comprising a first communication device for transmitting signals in which some signals in a frequency band have been removed, and a second communication device for receiving the transmitted signals, wherein the second communication device determines the signals to be removed by the first communication device, and transmits information indicating the positions of the signals to be removed as determined, and wherein the first communication device receives the information indicating the positions of the signals to be removed, removes some signals in a frequency band on the basis of the information, and transmits the resulting signals, thereby enabling clipping that corresponds to the conditions of a propagation path.
