Abstract :
The performance of the frequency division duplex (FDD) mode of the code division multiple access (CDMA) based Universal Mobile Telecommunication System (UMTS) is investigated. The new call blocking and call dropping probabilities, the probability of low-quality access as well as the required average transmit power are quantified both with and without the assistance of adaptive antenna arrays as well as with and without encountering shadow fading. In some of the scenarios investigated, the system´s user capacity is doubled with the advent of adaptive antennas
