摘要： A method and apparatus is provided for calculating possible values of a combination ratio for signals received via a plurality of antennas (A1 to An) according to different algorithms by means of a plurality of algorithm units (31 to 33), calculating an SIR value for each of a plurality of composite signals which are generated using the possible values, respectively (SIR calculation units (41 to 43)), determining which composite signal has the highest quality (determining unit (44)), and selecting the composite signal having the highest quality as a received signal (selecting unit (45)). Thus, since one composite signal with the highest quality is selected as the received signal from among the plurality of composite signals acquired according to the different algorithms, when the weight calculation according to either of the different algorithms becomes unstable or results in an erroneous convergence, the composite signal according to this algorithm is not selected and another composite signal according to another algorithm is selected. Accordingly, the weight calculation can be maintained with stability, and erroneous convergences of weights can be prevented.

摘要： A receiver applied to a mobile communications system which allows reduction of circuit scale is provided. Each of a plurality of fingers has a phase estimator. The phase estimator determines a phase estimate based on demodulated signals restored via a despreading section. The phase estimate is given to a compensation coefficient operation section via and I/O section. The compensation coefficient operation section determines a weight/phase compensation coefficient used for realizing both weight control and phase compensation control based on the phase estimate. A finger has a phase compensator. The phase compensator multiplies the demodulated signal after delay compensation by the determined weight/phase compensation coefficient. As a result, weight control and phase compensation control can be simultaneously attained. In this way, circuit scale can be reduced compared with the case in which weight control and phase compensation control are made individually via separate circuits.

摘要： In an apparatus and method for controlling an array antenna comprising a plurality of antenna elements arranged so as to be adjacent to each other in a predetermined arrangement configuration, a plurality of received signals received by the antenna elements is transformed into respective pairs of quadrature baseband signals, using a common local oscillation signal, wherein each pair of quadrature baseband signals is orthogonal to each other. Then predetermined first and second data are calculated based on each pair of transformed quadrature baseband signals, and are filtered using a noise suppressing filter. Respective elements of a transformation matrix for in-phase combining are calculated based on the filtered first and second data, and the received signals obtained from the each two antenna elements are put in phase based on the calculated transformation matrix. Thereafter, a plurality of received signals which are put in phase are combined in phase, and an in-phase combined received signal is outputted.
