FHT在WCDMA辅同步中的应用及FPGA实现
FHT in WCDMA Secondary Synchronization and FPGA Based Implementation
快速哈达马变换（Fast Hadamard Transform）广泛应用于WCDMA小区搜索的辅同步运算。本文给出了FHT法和传统直接相关法等效的证明，论证了与直接相关法相比，FHT大大降低了运算复杂度。并提出一种基于FPGA的辅同步实现方案，实现中使用查找表法简化了相关值运算的复杂度，节省了硬件资源。
FHT(Fast Hadamard Transform) is widely adopted in WCDMA Secondary Synchronization. In this paper, we first demonstrate that FHT is equivalent to traditional correlation method with the same correlate result, however, with lower complexity. Then we propose a FPGA based implementation of WCDMA Secondary Synchronization. LUT (look-up-table) is used in correlate computation as a method to save FPGA resource.
