Study on direction finding based on smart antenna communication

Hao Jing-tao

Abstract

The TD-SCDMA criterion adopts smart antenna,in which how to improve its location precision is the key problem.A new direction-finding method was proposed based on the CDMA system with eight-array smart antenna.According to the characters of switched beam antenna,it employed the characters of signal power to estimate the orientation angle.The system is simple in computation and suitable for TD-SCDMA.The capacity of the system is greatly increased.The simulation proves that the location precision of the system is higher.
