摘要/Abstract

摘要： 根据WCDMA主同步信道的帧结构,利用主同步码的构成特点改进了传统匹配滤波器的结构,提出了一种二维级联匹配滤波器结构。并对该结构进行了定点仿真,通过FPGA实现了这种匹配滤波器。该二维级联结构大大节省了硬件资源,提高了运行速度。

Abstract: A novel two-dimension concatenate matched filter isproposed according to the frame structure of primary synchronous channel and the feature of PSC. We simulate this architecture. Moreover, FPGA chip design is accomplished. It is verified that this matched filter can reduce thehardware resource and improve the operation speed.

Key words: wideband code division multiple access, primary synchronization code, two-dimension concatenate matched filter
