本文首先回顧了基于小波分析理論的基帶波形成形理論，提出了基于FPGA 的實(shí)現(xiàn)結(jié)
構(gòu)。采用Altera 的Cyclone (EP1C12Q240C6)進(jìn)行實(shí)現(xiàn)。利用Quartus5.0 和進(jìn)行結(jié)構(gòu)設(shè)計(jì)
和仿真。結(jié)果證明，這種結(jié)構(gòu)可有效對信號進(jìn)行成形及解成形處理，節(jié)約頻帶利用率，為基于小波分析理論的基帶波形成形的實(shí)用化打下基礎(chǔ)。

The digital signal wavelet shape based on FPGA Abstract: This thesis reviews the theories of wavelet-based coder-decoder. Provide the structure wavelet-based coder-decoder based on FPGA. Realize it utility Cyclone (EP1C12Q240C6). The simulation of Quartus show that this structure can effectible shapes and deshapes the based signal and economizes the efficiency of the frequency band. It lays a good foundation for the application of the wavelet-based coder-decoder.
