摘要
提出了一种双通道实时数据采集处理系统的设计与实现方案,该系统以TI公司的DSP芯片TMS320C31和TLC320AD50C为核心器件,实现了32位浮点计算和16位数据采集与回放,而且具有两个独立的A/D和D/A通道,将该系统嵌入到单边带电台接收机中,构成的单边带电台接收机自适应抗干扰系统,实现了实时自适应噪声抵消,能够显著提高信噪比。
A scheme to design and implement a dual channel real time data acquisition and processing system is presented. This system utilizes TI' s DSP TMS320C31 and TLC320AD50C as the main chips and works with two independent A/D and D/A channels. It can implement 32-bit floating-point operation and 16-bit data acquisition and playback. Embedded with the designed system, a single side-band receiver adaptive anti-jamming system is constructed. It realizes real time adaptive noise cancellation and improves the signal-to-noise rate significantly.
