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 b efore despreading procedure does not increase but even decreases the perfor mance than that with an omni-directional antenna, and the cause of this ser ious performance degradation is revealed. Then it is shown that the perform ance with the weight control scheme based on the signal after despreading p rocedure is always better than that with an omni-directional antenna. Furth ermore, the possibilities of performance improvement by the combination of adaptive array antenna and interference cancellation techniques are mention ed.
