    Abstract: The variation cycle L of the characteristics of a transmission line is divided into a plurality of sections (n sections), a procedure is repeated in which transmission line estimation is performed for only one section among n sections in one beacon period, and thus transmission line estimation is performed for all of the n sections. The beacon period T is set based on (T=L×m/n), where n is an integer that is 2 or larger, and m is an integer that is n or larger and whose greatest common measure with n is 1.

    Abstract: A communication device capable of correcting a burst error exceeding a correcting capability of an error correcting code by only transmitting one packet. With respect to data to be transmitted, a frame generating section 22 generates a frame for which an error detecting process, etc., is performed. A frame dividing section 23 divides the generated frame, by a predetermined number, into a plurality of divided frames. A transmission control section 24 generates a packet in which the plurality of divided frame are copied predetermined times. A transmitting section 25 sends the packet to a receiver. A receiving section 35 receives the packet transmitted from a transmitter. A reception control section 34 divides the received packet by the predetermined number. A frame reconstructing section 33 reconstructs the frame by assembling the divided frames in predetermined order. A frame processing section 32 performs an error correcting process, etc., for the reconstructed frame.

    Abstract: 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.

    Abstract: The present invention is intended to exactly extract a feature-region along its contour line without erroneously extracting any moving object other than the feature-region. An extraction signal from a feature-region main-portion extracting circuit is sent to a small region eliminating circuit whereby an erroneously extracted small region is detected and eliminated as an erroneously extracted noisy portion. The small region eliminating circuit compares a small region with four detection patterns, discriminates it as a region other than the feature (face)-region if no match is found and causes a center pixel of a window of 3×3 pixels to have a logical value of zero. An output of the small region eliminating circuit is sent to a blank filling circuit which compares its input with four detection patterns, discriminates it as a face-region if a match is found and makes a central pixel of a window of 13×13 pixels have a logical value of 1. The above-mentioned extraction method can reliably extract features of the face-region and is free from the erroneous extraction of any moving object other than the face.
