Abstract
In a mobile communication terminal for performing wireless communication by receiving wireless signals according to CDMA communication system containing pilot signals by an antenna array containing a plurality of antenna elements (1-1 to 1-N), despreading processing is performed on received signals x1 to XN at each of the antenna array elements (1-1 to 1-N) according to a predetermined despreading code. An array response vector composed of pilot signals which are extracted by an array response vector detecting section for each of the antenna elements (1-1 to 1-N) represents the arriving direction of wireless signals. In order to form a directivity pattern of the antenna array containing antenna elements (1-1 to 1-N), a weighting operation is performed according to the array response vector. By doing this, it is possible to control the antenna array directivity pattern stably for performing wireless communication by receiving wireless signals according to a CDMA communication system.
