Kertas kerja ini membincangkan penggunaan antena tatasusunan suai di stesen pangkalan sistem CDMA Multi Processing Gain (MPG). Ia ditunjukkan bahawa antena tatasusunan suai dengan skema kawalan berat berdasarkan isyarat sebelum prosedur penyebaran tidak meningkat malah mengurangkan prestasi berbanding antena omni-arah, dan punca penurunan prestasi yang serius ini didedahkan. Kemudian ditunjukkan bahawa prestasi dengan skema kawalan berat berdasarkan isyarat selepas prosedur penyebaran sentiasa lebih baik daripada dengan antena omni-arah. Tambahan pula, kemungkinan peningkatan prestasi dengan gabungan antena tatasusunan suai dan teknik pembatalan gangguan disebut.

Abstract: This paper discusses the employment of adaptive array antennas at the base station of a Multi Processing Gain (MPG) CDMA system. It is shown that the adaptive array antenna with the weight control scheme based on the signal before despreading procedure does not increase but even decreases the performance than that with an omni-directional antenna, and the cause of this serious performance degradation is revealed. Then it is shown that the performance with the weight control scheme based on the signal after despreading procedure is always better than that with an omni-directional antenna. Furthermore, the possibilities of performance improvement by the combination of adaptive array antenna and interference cancellation techniques are mentioned.
