摘要： To provide a space multiplex signal detection circuit capable of obtaining an excellent error rate characteristic by suppressing an increase in the circuit scale if when a modulation multivalued number is particularly increased in the case of receiving a signal subjected to space multiplexing to detect the signal. SOLUTION: A transmission signal candidate narrow-down circuit 108 refers to a proximity signal point data table 109 and stepwise narrows down the number of a plurality of transmission signal candidates to a prescribed number of the candidates. The proximity signal point data table 109 stores the cross-reference between signal points closer on a transmission constellation to signal points of transmission signals of each of transmission systems estimated by a transmission signal estimate circuit 107. A maximum likelihood estimate circuit 113 receives candidates of the transmission signal sequences and metrics corresponding to the candidates and outputs a transmission signal sequence whose metric value is least as a final transmission signal sequence.

摘要： In calculation of a position of a terminal, there arises, when creating a delay profile, a problem to select a transmission code for a sector of a base station to create the delay profile. According to a position of a base station and a bearing of each antenna forming a sector of the base station, a wireless position calculation method selects a transmission code for a sector of a base station to create a delay profile. Under a condition that the number of delay profiles to be created is limited, each delay profile is created in consideration of the antenna bearing. Therefore, the number of base stations at mutually different positions is increased to calculate the position and precision of the position calculation is improved.

摘要： A base station apparatus is provided for adaptively controlling a maximal accommodation channel number per unit area (for example, the coverage area of a cell or sector) in accordance with a traffic quantity without relying upon detachment of a mobile base station and installation of a repeater. Upon inputting of a plurality of baseband signals of a user channel-multiplexed channel group, linear coupling is performed by a weight which is different per area that outputs it, thereby enabling control of the channel density. Additionally, a per-group available channel number is constantly monitored to control the weight while using threshold judgment for the available channel number as a trigger, thus achieving situation-sensitive prompt handleability.
