摘要
介绍3G移动通信技术的发展和我国TD-SCDMA标准,及WCDMA与TD-SCDMA混合组网时,临近频率存在系统干扰问题。基于DSP芯片TMS320C5402的数字信号处理功能,借助Matlab程序设计语言,设计出FIR数字滤波器FIR数字滤波器,广泛地应用于数字信号处理领域。对FIR滤波器的工作原理和设计方法也进行了简单的介绍。
This article depicts the development of mobile communication technology of 3G and the standard of TD- SCD- MA. The interference issue between systems exits the nearby frequency when WCDMA and TD - SCDMA are assembled. To aim at this topic, the FIR digital filter is designed based on the disposed function of digital signal on the DSP chip TMS320C5402 with the benefit of Matlab programming language. The FIR digital filter is being used in the disposed digital signal sphere widely, the principle of work and the designed method of the FIR digital filter are introduced in a nutshell.
