In this paper, Bit Error Rate (BER) performance of Feedback-type Adaptive Array Antenna (AAA) in Frequency Division Duplex/Direct Sequence Code Division Multiple Access system (FDD/DS-CDMA) with Mobile Station (MS) reception diversity will be investigated. The results include the effects of maximum Doppler frequencies (fd) and antenna element spacing at Base Station (BS) under flat fading and frequency selective fading. These effects are not clarified until now on this system. Moreover, the effect of rake receiver will be studied on this system. Computer simulation results show that the reception diversity shows better BER performance than single antenna reception at MS due to diversity effect.
