    Abstract: PROBLEM TO BE SOLVED: To make it possible to use a transmission rate in accordance with the transmission quality of a wireless transmission path. SOLUTION: In an AP having a wireless communication function capable of using a plurality of transmission rates, a medium utilization-factor calculation section 211 of a MAC circuit 111 calculates a utilization factor of a wireless transmission path through which wireless communication is performed using the wireless communication function, and supplies the calculated utilization factor to a transmission rate determination section 202. The transmission rate determination section 202 determines a transmission rate at least on the basis of the utilization factor supplied from the medium utilization-factor calculation section 211. The present invention is applicable to APs constituting a wireless LAN system. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To enhance a reception characteristic of a terminal by compensating degradation in transmission quality independently of a mobile speed of the terminal. SOLUTION: In the case the terminal receives a transmission signal via a wireless transmission channel and demodulates data by applying various reception processing to the received signal, the terminal receives mobile speed information from a speed detection means detecting a mobile speed of the terminal itself to control the reception processing with respect to the received signal in response to mobile speed information so that the terminal can execute the reception processing optimum to the wireless transmission channel of which state changes with the mobile speed of the terminal itself.

    Abstract: PROBLEM TO BE SOLVED: To enable an image processing system to easily and precisely recognize a specific position of a still body and an arbitrary position distance from the specific position in the best focus state with a small calculation quantity. SOLUTION: This position recognition device is a device which recognizes a specific position of an arbitrary still body and is equipped with recognized marks Mi (i=1 to 8) fitted at desired positions of the still body, an image pickup means 6 which picks up an image of the recognized marks of the still body, and an arithmetic means 7 which finds position information on the recognized marks Mi by performing an image process with the luminance signals of the recognized marks Mi picked up by the image pickup means 6; when one arbitrary recognized mark Mi is set as a target and the image pickup means 6 is put closer, the arithmetic means 7 finds information on the distance between the target recognized mark Mj and image pickup means 6 according to the position information on the target recognized mark Mj and arrangement information on other recognized marks Mi.

    Abstract: PROBLEM TO BE SOLVED: To enable phase estimation of fading to be performed at high speed. SOLUTION: A phase decision surface operation circuit 21 reads a pilot block back and forth of a current time slot from a memory 20 and operates a reference phase plane (a phase of a QPSK carrier wave) on the basis of that. From the discriminated reference phase plane, it is decided whether or not it is a high-speed fading. When it is judged to be the high-speed fading, the reference phase plane is corrected on the basis of the phase differential information outputted by an adder 30 of a control circuit 24.

    Abstract: PROBLEM TO BE SOLVED: To efficiently transfer a received packet to an upper layer with a low delay.SOLUTION: A communication apparatus comprises a reception part that receives a packet, a response transmission part that, every time a packet group including two or more packets is received, transmits a response packet including information concerning a packet having an error occurring of the packet group, a packet transmission part that transmits a packet having no error occurring to an upper layer, and an error correction part that uses data of the packet having no error occurring to restore data of the packet having the error occurring. The response transmission part detects from the packet having no error occurring of the packet group a packet last received by the reception part, and transmits a response packet indicating that all the packets received prior to the detected packet have no error occurring.
