摘要

本文从能量效率的角度对无线自组织网络的不同调制方案进行了比较分析。基于AWGN和非频率选择性慢瑞利衰落信道的总能耗，对MPSK、MFSK和MQAM进行了比较。最后通过详细的数学计算和仿真，证明了在衰落信道下，通过优化特定距离下的传输时间和星座大小，可以提高能量效率。

Comparative Analysis of M-ary Modulation Techniques for Wireless Ad-hoc Networks

This paper presents a comparative analysis of different M-ary modulation schemes for wireless ad-hoc networks based on energy efficiency. It compares MPSK, MFSK, and MQAM on the basis of total energy consumption in the AWGN and non-frequency selective slow Rayleigh fading channel. Finally under detail mathematical calculations and simulation, we justify that the energy efficiency can be improved even under a fading channel by optimizing transmission time and constellation size at a particular distance.
