Method, and the ecad frequency complement spreader which uses this and uses this the transmitter-receiver which select the frequency basis zone of the spread mark

摘要

Topic It regards the ecad frequency complement spreader which uses frequency complement basis zone in the communication system which designates the human body as medium, and the transmitter-receiver which uses this.SolutionsThis invention uses the human body as the communication channel, by the fact that frequency zone of the spread mark which be adapted is used for data communication with the channel quality and noise environment of the human body which changes between the communication devices which it is connected with the human body in regard to human body communication method and the system which use frequency complement basis zone in order sending and receiving to do the data, with peripheral environment, is selected, converts the performance of frequency complement supuretsudeingu maximally, increases the processing profit of spread mark technology and the human body user not only decreasing interference mutually, is induced from the other electronic equipment strong interferenceAt the time of a certain, it is low electric power and there is an effect which can form the human body communication which is stabilized.
