Study on Direction Finding Triangulation Based on Smart Antenna CDMA System

This paper proposes a new direction-finding and location method based on the CDMA system with eight ele- ments smart antenna array.According as the characters of switched beam antenna,it employed the characters of signal power to estimate the angle and employed direction finding triangulation location to estimate the location.This paper in- vestigated the performance of the system in multi-environment that considered channel fading,multi-channel,none-of- light and multi-user interference.The system is simple and increases the system capacity,can be applied to TD-SCD- MA.The simulation proves the location precision of the system is higher.
