一种WCDMA前导实时检测方法及其FPGA实现
A Real-time Preamble Detection in WCDMA System and Its FPGA Implementation
摘要
Abstract
Considering the large time windows and doppler frequency offset in the reconnaissance for WCDMA signals,a real-time detection algorithm in frequency domain is proposed by analyzing the preamble detection algorithm in the commercial WCDMA network.Segmented FFT and incoherent integration are introduced in order to shorten processing time and possess better anti-frequency offset performance.The detection performance of this algorithm is verified by a series of simulation results.Finally,the ModelSim simulation and hardware resource occupation of this algorithm are given in this paper.关键词
