基于DSP的自适应滤波器的设计，在CCS DSK C5000软件环境下，用C语言描述了自适应滤波器的结构。在TI公司的TMS320C54X系列的TMS320C5402芯片上，完成了基于LMS自适应算法的FIR横向滤波器的设计,并进行了模拟仿真，得出了正确的结果。仿真结果表明，应用LMS算法的自适应滤波器不仅可以实现对信号噪声的自适应滤除，还能用于系统识别。-The Design of Self-adaptive Filter Based on DSP，Under the circumstance of CCS DSK C5000 software, the adaptive filter is described and designed by C language. Ultimately the design of the LMS algorithm horizontal structural FIR filter is realized using TMS320C5402 device of TMS320C54X family of TI Company, the simulation is done and also the results is correct.

Results of simulation show that this kind of adaptive filter not only can be used to filter the signal noise, but also recognize the system.
