The interference reduction capability of antenna arrays, base station assignment and the power control algorithms have been considered separately as means to increase the capacity in wireless communication networks. In this paper, we propose base station assignment method based on minimizing the transmitter power (BSA-MTP) technique in a direct sequence-code division multiple access (DS-CDMA) receiver in the presence of frequency-selective Rayleigh fading and power control error (PCE). This receiver consists of constrained least mean squared (CLMS) algorithm, matched filter (MF), and maximal ratio combining (MRC) in three stages. Also, we present switched-beam (SB) technique in the first stage of the RAKE receiver for enhancing signal to interference plus noise ratio (SINR) in DS- KEYWORDSAdaptive beamforming, base station assignment, DS-CDMA, power control error, matched filter, maximal ratio combining

“…In fixed beamforming, the M element transmit antenna array is fed with M mutually orthogonal weight vectors, which result in an M -fold orthogonal beam pattern [9]. The users are allocated to each beam on the basis of maximizing the received signal power, and they can be switched dynamically, depending on their movements [10]. The measured radio channel data used in Section III-B were recorded for static locations, which renders fixed beamforming more relevant to this analysis than a more complex adaptive beamforming scheme.…”
