摘要

本文提出一种新的调制方法——非正交多重调制(NOMM)

并利用信号估计理论对其进行分析.在此基础上

以信号星座图为工具

构造出多种优良的调制方法

并分析了相应的差错性能和频带利用率.数值计算结果表明

由于突破了正交的限制

从而使这些全新的多重调制方法较之传统方法有更高的频带利用率.不仅在实际上提出了更有效的方法

也从理论上为调制技术指出了更宽的发展方向.

Abstract

A novel modulation technique is proposed in this paper

Non-orthogonal Multiple Modulation(NOMM).Based on estimation theory analysis

various well-performed modulation methods are presented in terms of signal constellations.Relevant error probability and bandwidth efficiency are also discussed.The result of numerical experiments shows that these completely new multiple modulations outperform the conventionals in bandwidth efficiency

which is owed to the unrestrainedness in orthogonality.NOMM offers a more effective method in practice and indicates a broad perspective of development for modulation techniques in theory as well.
