Abstract: A channel estimation circuit (12) of an individual CH path demodulation unit (1A-1L) performs a channel estimation from an individual CH. A channel estimation value correction circuit (22) of a shared CH path demodulation unit (2A-2L) then corrects a reception power fluctuation due to uplink transmission power control which is caused by the timing offset between the individual CH and the shared CH. The resultant data is used for the demodulation by a shared CH demodulation circuit (23).

Abstract: A station divides all CHs available for assignment to an AP into a plurality of groups. CHs being included in one group are checked to determine whether or not there exists an AP that uses each of the CHs included in one group, based on an instruction of background scan from an OS and the like. Further, for CHs being included in the next group, the station checks whether or not there exists an AP that uses each of the CHs included in the next group based on the next instruction of background scan from an OS. As a result, the time required for one background scan can be reduced so as to have less impact on the communication the station is performing.

Abstract translation: 站点将可用于分配的所有CH分成多个组。 根据来自OS等的背景扫描的指示，检查包括在一个组中的CH以确定是否存在使用包括在一个组中的每个CH的AP。 此外，对于下一组中包括的CH，站基于来自OS的下一个背景扫描指令来检查是否存在使用包括在下一组中的每个CH的AP。 因此，可以减少一次背景扫描所需的时间，从而对台站正在进行的通信的影响较小。

Abstract: The N peaks are selected from a delay profile in order starting from the highest peak involved in the delay profile, the path level and path timing are determined for each of the selected peaks, and the identical paths individually responsible for different delay profiles are detected by comparing the path timings calculated for the preceding time and the path timings calculated for the present time. Based of the path levels calculated for the preceding time and the path levels calculated for the present time, averaged path levels are computed on a path-by-path basis for the present time, a predetermined threshold is applied to the computed average path levels, and the paths to be allocated to the fingers are selected. Of the path timings that have been obtained for respective selected paths, the latest path timings are allocated to the fingers as synchronization timings.

Abstract: According to a transmitter-receiver of a mobile communication system of the present invention, it is possible to preferably perform the communication with a desired user without deteriorating the quality of service of an interference user even when the desired user and the interference user are present in the same direction. Therefore, by selecting a path level on a two-dimensional profile larger than a predetermined threshold or a path having the ratio of signal power to interference power or signal power larger than the predetermined threshold, a plurality of paths respectively having preferable reception quality are selected. Then, interference powers included in received signals of the paths are calculated, a path having minimum interference power is selected, and the DOA of the path is used as a downlink-signal transmitting direction.

Abstract: In a CDMA receiving apparatus according to the present invention, a delay spread calculation unit calculates a delay spread based on timings and levels of paths equal to or higher than a path level threshold, and a same-path detection time range calculation unit calculates a same-path detection time range in accordance with the delay spread. A finger-assigned path selector unit selects finger-assigned paths from paths equal to or higher than the path level threshold starting in order from the one having the highest path, and excludes paths within the same-path detection time range centered at each selected path, from candidates for finger-assigned paths, from the next selection onward. Then, a demodulation processing unit demodulates a received signal using the path timings of the finger-assigned paths as synchronization timings.

Abstract: A station (STA) that performs communication with an access point includes an FCS error detecting section that detects an error of all packet data of received data on hardware and a CRC error detecting section that extracts data addressed to the STA from received data through a MAC filter to detect an error of extracted data again on software. An SME compares the error values detected through the two error detections to each other, detects, based on the comparison result, whether or not interference of an interfering wave exists, and causes a utility to display a status of interference. In addition, the SME instructs a hardware section to change a channel used for communication.
