<p>PROBLEM TO BE SOLVED: To provide a communication device, a communication system and a communication method, having a power saving function to shift to power saving operation, when judging, at the reception processing of a preamble positioned at the top of a frame in an existing communication standard, whether or not the frame is a reception target and when the frame is not the reception target.SOLUTION: The communication device includes: frequency deviation information management means 202 for storing a frequency deviation pattern for each terminal of a reception target; frequency deviation estimation means 208 for estimating the frequency deviation pattern of a reception signal; and judgment means 209 for identifying a transmission source on the basis of the estimated frequency deviation pattern of the reception signal by referring to the frequency deviation information management means, and for judging whether or not to perform demodulation processing on the reception signal.</p> |
