The performance of circular SA in CDMA application

This paper analyzes the performance of circular SA with 8 array elements in different application scenarios. For more code-channels pointing to different directions, according to the combination of the chip data, the directions for the main and side beam-lobes will change suddenly, which is hard to forecast. It is founded that the RAKE receiver couldn´t been used to compensate for the effect of multi-path fading, making the instability of system rising suddenly. By which it can be shown that this SA transmission system for multi-directions is only suitable for walking mobile communication system with smaller covering range.
