摘　　要：针对数字化基带成形滤波的信号处理特点 ,将截短的基带波形进行二维分解 ,得到成形滤波器的多相结构。通过对多相结构的分析 ,给出了一种较为精简实用的基于滤波器系数查询表模式的FPGA实现结构 ,该结构具有实现简单、占用资源少等特点。仿真结果表明 。According to the signal processing characteristics of the digitized baseband shaping, the 2-dimension decomposition for the truncated baseband sequence is made, and the poly-phase structure for the shaping filter is derived. By analyzing the poly-phase structure, a simple and feasible structure implemented with FPGA is proposed, which is based on the look-up table of the filter's coefficients. The structure has the advantages of simplicity in implementation and saving resource in hardware. The computer simulation results show that the implementation method can meet the practical need.
