Title:
APPARATUS AND METHOD FOR COMMUNICATING AS WELL AS INFORMATION RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP3404530
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for communicating suitable to rapidly detect an interference from neighboring transmission terminals in a radio communication system.
SOLUTION: A BSG 102 of the apparatus 101 for communicating receives an input of a data signal. A modulator 103 modulates the data signal, transmits an up-converted signal by a radio transmission. A zero-crossing timing extractor 201 extracts zero-crossing timing of the modulation signal, switches an extraction switch 202, and acquires the intensity or a power of the zero-crossing timing of the received ratio signal. An averaging unit 205 outputs a time mean of the acquired intensity or the power as the intensity or the power of the detected interference signal.
