摘要

本文提出了一种新的多电平非正交脉冲形状调制(NPSM)方法，该方法基于长球面波函数(PSWF)，利用频谱重叠获得了优异的功率谱特性，并利用帧函数的完整特性有效地消除了码间干扰，同时提高了系统的频带利用率。本文还给出了D2D非正交多路接入(NOMA)中继无线系统的结构，该系统可以用遗传算法进行解码。通过对不同环境的仿真，表明该编码比传统的QAM具有更高的频谱效率和3dB输出性能

Non-orthogonal Pulse Shape Modulation for Wireless Relay D2D Communication

This paper presents a novel multilevel Nonorthogonal Pulse Shape Modulation (NPSM) method, which based on the prolate spheroidal wave function (PSWF) and utilizes the spectral overlap to obtain the excellent power spectrum characteristic, and utilizes the complete characteristic of the frame function to effectively eliminate the inter symbol interference while improving the system band utilization rate. We also give the architecture used for D2D Non-Orthogonal Multiplex Access (NOMA) relay wireless system, which can be decoded by genetic algorithm. Through simulation different environments, it shows such codes have higher spectrum efficiency and 3dB out performance over the traditional QAM
