【Abstract】 A new beam forming method for switched beam smart antenna application in a CDMA system is proposed.The working principle and blocking characteristic of a new smart sector system based on it are also studied.Simulations show that our beam forming method outperforms two traditional ones.The proposed smart sector system can obviously improve the trunking efficiency,especially when users’ DOA follows nonuniform distribution.更多还原
