摘要

本文对不同的调制技术进行了比较研究，以提高LTE环境下的应用性能。本研究对4G LTE标准进行了深入研究，以更好地识别其性能特征。LTE (Long Term Evolution)是4G移动通信中用于移动电话和数据终端的高速无线通信数据传输的技术。基于信道功率、占用带宽、相邻信道功率、基于统计互补累积分布函数的平均功率和信噪比等参数，讨论了QPSK、16QAM和64QAM等调制技术。从结果可以看出，QPSK提供了更好的平均功率，16QAM提供了更好的信道功率，而64QAM提供了最低的噪声功率、相邻信道功率、最低的占用带宽和最大的信道容量。

Comparative analysis of different modulation techniques of LTE network

This paper presents a comparative study on different modulation techniques to enhance application performances in the context of LTE. This work presents a close examination of 4G LTE standard to recognize better the performance characteristics. Long Term Evolution (LTE) is used in 4G mobile telecommunication for high speed wireless communication data transfer in mobile phones and data terminals. Modulation techniques such as QPSK, 16QAM and 64QAM are discussed based on the parameters like channel power, occupied bandwidth, adjacent channel power, average power based on statistical complementary cumulative distribution function, and signal to noise ratio. From the results it is observed that QPSK provides better average power, 16QAM provides better channel power but 64QAM gives lowest noise power, adjacent channel power, lowest occupied bandwidth and maximum channel capacity.
