    摘要： A transmission channel selection method includes: collects information for calculating evaluation values of each of a plurality of transmission channels, and calculates separate evaluation values of the transmission channels individually with respect to each of a plurality of mobile stations; reduces the number of candidates for the transmission channels with respect to the plurality of mobile stations using the separate evaluation values; collects information for jointly calculating evaluation values of the transmission channels with respect to at least one of the plurality of mobile stations, and calculates the joint-separate evaluation values; and selects the communication paths of the plurality of mobile stations using the separate evaluation values and the joint-separate evaluation values.

    摘要： A wireless communication system (1) includes a base station (200), one or a plurality of RNs (300) associated with the base station (200), and one or a plurality of mobile stations (100). When the mobile station (100) and the base station (200) communicate without going through the RN (300), the wireless communication system (1) uses a first transmission power control method to control the transmission power of the mobile station (100), and, when the mobile station (100) and the base station (200) communicate via the RN (300), the wireless communication system uses a second transmission power control method to control the transmission power of the mobile station.

    摘要： In a CDMA receiving apparatus, a delay profile using a desired constraint length is generated by a delay profile generating unit from received signal wave-form data recorded on a received signal wave-form buffer unit. Several demodulation paths are selected at peak position of the delay profile by the path search unit. Demodulation symbols which are generated from received signal wave-form data of each demodulation path by the channel demodulating unit are brought into in-phase by an adjustment angle which is obtained by the channel estimating unit. If the reception quality which is measured by the reception quality measuring unit is lower than a predetermined value for a combined demodulation symbol which is combined by a RAKE unit, the combination of said selected demodulation paths or the constraint length is changed to repeat the demodulation operation of the same received signal wave-form data.
