摘要:

以32音并行体制为例,利用DSP平台实现了多音并行体制的调制端,给出了其主要模块的具体实现方法。由于并行体制技术成熟、成本低、高性价比对提高数据传输速率、消除多径衰落有益。

Abstract:

This paper takes 32-tone parallel modulation as an example to realize multi-tone parallel modulation with DSP hardware platform.The realization of its main modules is provided.Owing to its sophistication,low cost and high cost efficiency,the parallel mode is helpful in improving data transmission speed and eliminating multipath fading.

Key words: multi-tone parallel mode;modulation;FFT;DSP
