Makalah ini menyiasat pengaruh bilangan antena, perbezaan sudut antara arah ketibaan (DOA) isyarat yang diingini dan isyarat yang mengganggu, dan susunan antena pada prestasi BER bagi kepelbagaian tatasusunan antena adaptif koheren (CAAD) penerima dalam pautan terbalik DS-CDMA (W-CDMA) jalur lebar. Eksperimen mengandaikan pengguna mengganggu kadar tinggi telah dijalankan di dalam bilik radio anechoic menggunakan antena tiga sektor dengan pancaran 120 darjah (bilangan maksimum antena ialah enam). Keputusan percubaan menunjukkan bahawa tahap gangguan ditindas daripada pengguna kadar tinggi penerima CAAAD telah meningkat dengan ketara dengan meningkatkan bilangan antena, terutamanya apabila bilangan pengguna yang mengganggu adalah lebih besar daripada darjah kebebasan CAAAD. Ia juga telah disahkan bahawa walaupun prestasi BER penerima CAAAD meningkat dengan ketara berbanding dengan antena sektor tunggal, penambahbaikan itu menurun dengan ketara apabila perbezaan DOA antara isyarat yang dikehendaki dan isyarat mengganggu berada dalam kira-kira

Abstract: This paper investigates the influence of the number of antennas, the angle difference between the direction of arrival (DOA) of the desired signal and those of interfering signals, and the antenna arrangement on the BER performance of the coherent adaptive antenna array diversity (CAAAD) receiver in the wideband DS-CDMA (W-CDMA) reverse link. Experiments assuming high-rate interfering users were conducted in a radio anechoic room using a three-sectored antenna with a 120-degree beam (maximum number of antennas was six). The experimental results showed that the degree to which the interference was suppressed from high-rate users of the CAAAD receiver was significantly increased by increasing the number of antennas, especially when the number of interfering users was larger than degree of freedom of the CAAAD. It was also verified that although the BER performance of the CAAAD receiver significantly improved compared to a single sectored antenna, the improvement remarkably decreased when the DOA difference between the desired signal and interfering signals was within approximately
