摘要

随着数字通信应用中复杂调制方案的发展，需要强大的数字信号处理(DSP)硬件来满足计算需求。本文介绍了一种基于德州仪器TMS320C40处理器的多载波解调器的设计与开发。在本应用中，商用DSP板被配置为具有8个并行通道的多载波FSK信号，具有各种调制参数。当前工作的目标是利用并行处理器的功能，期望通过使用部署在每个DSP模块上的增强算法，将来可以解决更复杂的解调方案。

Parallel DSP application in multicarrier FSK demodulation

The evolution of complex modulation schemes in digital communication applications brings with it the need for powerful digital signal processing (DSP) hardware to cope with the computational requirements. This paper describes the design and development of a multicarrier demodulator using four Texas Instruments TMS320C40 processors. In this application, a commercial DSP board is configured to demodulate a multicarrier FSK signal having eight parallel channels, with a variety of modulation parameters. The goal of the present work was to harness the power of parallel processors with the expectation that more elaborate demodulation schemes could be tackled in the future through the use of enhanced algorithms deployed on each of the DSP modules.
