Abstract: A scheme to design and implement a dual channel real time data acquisition and processing system is presented. This system utilizes Tl’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 and16-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.

Key words: adaptive noise cancellation, real time signal processing, digital signal processor
