Abstract :
In this letter, simulated annealing (SA) is used for designing a fixed multibeam antenna array (AA) in a multiuser radio wide-band code-division multiple-access (WCDMA) system. The method can be used dynamically in a real system and/or in a radio planning tool. The proposed method is applied on a linear array by designing the antenna element (AE) pattern, the number of fixed beams, the AE spacing, and the AA transmit weights. The proposed method leads to a substantial base station (BS) power reduction which can be used to increase the system capacity or data throughput in a WCDMA system.
