摘　　要：多速率信号处理系统是数字上变频处理的核心技术之一。多速率信号处理技术在解决匹配信号数据速率和保持传输信号波形有着明显优势。本文介绍一种利用基带成形滤波器和多级半带插值滤波器组成的多速率信号处理系统。通过FPGA设计系统,利用modelsim仿真验证系统,得出结论,设计的多速率信号处理系统满足信号速率匹配和保持传输信号波形的设计要求。Multi-rate signal processing system is one of the core technology of digital up conversion processing. Multi-rate signal processing techniques in solving the match signal data rate and maintaining the transmission signal waveform has obvious advantages. This paper describes a multi-rate signal processing system which uses baseband shaping filter and multi-level half-band interpolation filter. By FPGA design system, using modelsim simulation system, concluded that, multi-rate signal processing satisfies systems signaling rate matching and maintain the transmission signal waveform.
