| 20090167311 | Adaptive Array Wireless Communication Apparatus and Method of Same - An adaptive array wireless communication apparatus able to suitably select antenna elements, small in amount of processing, fast in convergence speed, and suitable for transmission/reception, and a method of the same, which controls the directionalities of array antenna elements based on array weights, controls an antenna element selecting unit 23 so that the antenna elements are intermittently determined, and adjusts a period of determination of the antenna elements based on information of the antenna elements determined at a controlling unit 26. | 07-02-2009 |
| 20100135223 | Wireless Communication Method and Wireless Communication Apparatus - When wireless communications are performed with a plurality of wireless stations using a spatial division multiple access scheme, there are included a moving speed grasp step, a priority grasp step, a channel assignment order determination step, a channel assignment order adjustment step for modifying, based on the priority grasped by the priority grasp step, so that the high-priority wireless station is placed high in the channel assignment order and a channel assignment control step for controlling, for the wireless stations after the wireless station to which a channel for frequency division multiple access has been assigned based on the channel assignment order, so that at least a channel for spatial division multiple access which has been spatially divided for the last channel is assigned. | 06-03-2010 |
| 20100136915 | Wireless Communication Method and Apparatus Therefor - A wireless communication method for a wireless communication apparatus to communicate wirelessly with a corresponding wireless communication apparatus with adaptively selecting a modulation scheme from a plurality of modulation schemes, comprising: a step of grasping a quality of a received signal; a step of selecting a first modulation scheme based on the grasped quality of the received signal; a step of calculating a retransmission rate of received signals in the first modulation scheme; a step of determining an estimated throughput from the calculated retransmission rate based on relations between throughput and retransmission rate; a step of comparing the estimated throughput with a throughput in a second modulation scheme having a smaller multi-value number than that in the first modulation scheme; and a step of performing wireless communication in either the first modulation scheme or the second modulation scheme depending on the comparison result. | 06-03-2010 |

| 20100013707 | Array Antenna Apparatus and Signal Processing Method - An array antenna apparatus which has an away antenna formed by a plurality of antenna elements, and subjects received signals, which are received by the antenna elements, to weighting using array weights of complex numbers. The array antenna apparatus includes a delay device for delaying a signal; a weighting device for separating ea of the received sirs into first and second received signals, delaying any one of the first and second received signals by using the delay device, so as to weight the first and second received signals at different timings; and a first adding device for adding the weighted first and second received signals to each other. The weighting device weights any one of the first and second received signals by using the real part of the relevant array weight, and weights the other received signal by using the imaginary part of the array weight. | 01-21-2010 |

| 20090295637 | Adaptive Array Antenna Apparatus and Adaptive Control Method Therefor - An adaptive array antenna apparatus for performing adaptive control based on received signals received by a plurality of antenna elements which form an array antenna. The apparatus includes a computation part for computing an error of the received signals at different timings; an error comparison part for comparing the errors at the different timings with each other; and a weighting synthesizing part for performing weighting synthesis based on results of the comparison. Based on the results of the comparison, the computation part releases at least a part of computation resources required for the computation of the errors, and terminates the computation of the errors. Typically, the computation part performs the release of the computation resources when it is determined that the error has a minimum value, and terminates the computation of the errors. | 12-03-2009 |
