摘要
生命信号作为一种微弱地低速目标信号,是一个频率极低、准周期、低信噪比、多谐波组合的信号。本文提出了利用ADI公司高性能的ADSP-TS101S处理器进行设计的数字信号处理终端模块的设计方案,同时给出功能结构框图,并简单介绍了ADSP-TS101S的功能结构和特点,以及利用两片TS101S所要完成的对生命信号的积累抽样、工频滤波、FFT分析和利用传统小波变换滤波的信号处理新算法,并给出仿真结果。
A weak and low speed target signal, life signals are built on the harmonic mode with a very low frequency, sem-period and low SNR. This paper presents a scheme for using the ADSP-TS101S processor by ADI Company to design a digital signals processing terminal module with its function frame given. It also introduces the functions and characteristics of ADSP-TS101S in brief. Finally, it discusses how to achieve accumulation sampling of life signals by using two TSI01 S, how to achieve frequency filtering and FFT analysis and how to cope with the new algorithm with signals filtered through traditional wave-transform and presents emulation results.
