摘　　要：用计算机仿真的方法研究了离散多音频系统DMT的的各模块功能。分析了信道编译码方法、交织与解交织及DMT调制与解调等关键技术。还把计算机仿真的结果与实验系统的结果作了比较,实测结果表明,仿真系统的性能达到了较理想的水平。Discrete multitone system performance has been studied by computer simulation. The error correcting encoding and decoding, interleave and deinterleave, and DMT modulation and demodulation are analyzed in detail. It is concluded that the performance of the experiment system achieves a fairly ideal level by comparing with the results of the computer simulation.
