Title:
COMMUNICATION APPARATUS AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2004/021617
Kind Code:
A1
Abstract:
There are included a transmission modulation part (103) for impulse-modulating the data to be transmitted, thereby producing a subcarrier; a subcarrier control part for controlling the subcarrier to be utilized for communication, depending on the amount and significance of information and on the propagation condition of communication; and an antenna part (101) for radiating the subcarrier signal. This structure allows selection of a subcarrier suitable for information to be transmitted and for propagation environment, and hence allows a communication to be performed which exhibits a high flexibility and a high noise immunity. Thus, there can be provided a communication apparatus that can perform a high-quality, high-stability communication exhibiting an improved disturbance immunity and that performs a flexible impulse communication.
