葛小慧 %A 黄爱苹 %A 胡荣 %J 电子与信息学报 %D 2003 %I %X SIR-based preamble detection is investigated under multipath fading condition. Two-antenna receiver is designed for the random access channel and common packet channel in WCDMA uplink. The preamble detection performance is derived and closed-form expressions are given. Three utilization methods of antennas' signals are compared by theoretical analysis and computer simulations. %K Preamble detection %K CDMA %K SIR estimation
