摘要： Under a multi-path environment, the receive timing for an incoming wave of the minimum propagation delay time cannot be accurately measured in the prior art. By using the delay profile created by delay profile creating section 102 and the first threshold value 330 received from the first threshold value calculation section 105, the first threshold value timing detection section 103 selects only the earliest receive timing exceeding the first threshold value, from all the timings that the correlation value in the delay profile becomes a maximum. By using the receive timing and the second threshold value 331 received from the second threshold value calculation section 107, the reference timing calculation section 106 selects the reference timing required for calculating the receive timing for the incoming wave of the minimum propagation delay time. The timing delayed by a previously set timing behind said reference timing is sent from the receive timing calculation section 108 as the receive timing 113 of the incoming wave of the minimum propagation delay time.

摘要： The invention intends to solve a problem that an S/I ratio of a signal from a target base station deteriorates when there is a terminal near another base station. For this purpose, a signal replica of the signal from the nearby base station is generated and the replica is subtracted from a receiving signal. A signal of the target base station is detected from the resultant receiving signal. The signal from the nearby base station is deleted from the denominator of the S/I ratio, thereby increasing the S/I ratio.

摘要： In a system having an uplink and a downlink differing from each other in communication capacity, an array weight for the downlink is estimated. An interference subspace for the downlink is constituted on the basis of bearing information collected from the uplink and transmission control information received from mobile stations. An optimum downlink array weight is estimated on the basis of an array response vector obtained from a signal subspace, and an interference subspace. The appropriate array weight enables the reduction of transmission power by which signals are transmitted by a base station and interference with other cells can be reduced. Consequently, line capacity is increased.
