COMMUNICATION TERMINAL AND METHOD FOR TIMING THE DETECTION OF COMMUNICATION-MEDIUM CHARACTERISTICS |
摘要 |
<p>The present invention is a communication terminal which modulates and demodulates a packet for transmission and reception based on a communication parameter for modulation and demodulation determined according to a communication-medium characteristic. The communication terminal according to the present invention includes: information-element extracting means which extracts, with each predetermined cycle, information indicative of either one of transmission efficiency and reception quality of the packet as an information element; difference calculating means which calculates, with each said cycle, a difference between a first information element extracted by the information-element extracting means and a second information element previously extracted by the information-element extracting means; and detecting-scheme performance determining means which determines, based on the difference between the first information element and the second information element calculated by the difference calculating means, with each said cycle, whether a scheme of detecting the communication-medium characteristic for changing the communication parameter is to be performed.</p> |
