Abstract:
1. A mobile communication terminal for performing wireless communication by receiving a wireless signal containing a pilot signal in accordance with a Code Division Multiple Access communication system, comprising: an antenna array having a plurality of antenna elements; a pilot signal despreading device for performing a despreading process on a received signal by the antenna element by a predetermined despreading code and extracting the pilot signal for each antenna element; a directivity-pattern-controlling device for performing a weighting operation so as to form a directivity pattern of the antenna array having a plurality of the antenna elements according to the pilot signal which is extracted for each antenna element by the pilot signal despreading device of the antenna elements and performing directivity control based on an obtained weight, wherein the directivity-pattern controlling device performs the weighting operation so the pilot signal received by each antenna element is correlated one by one to the corresponding weight, the directivity-pattern controlling device comprises a weighting factor calculating device for forming the directivity pattern of the antenna array wherein the pilot signal is used directly as the weighting factor for performing the weighting operation; and the weighting factor is determined by multiplying the pilot signal by a constant number.
