60GHz基带通信系统仿真(任务书,开题报告,外文翻译,论文16600字)
摘 要
随着科学技术的进步，当今世界，已然朝着信息时代发展，人类的生活已经离不开信息的传输。而通信系统随着时间的漂移也不断在更新换代，比如我们使用的手机，从前的1G，2G，3G而现如今，已经变为了速度更快的4G。尽管通信系统给人类的生活带来了很大的便利，但随着时代的发展，人们对它有了更高的要求。对于传输速率的研究从最初的Kbit/s，发展到Mbit/s，而现如今变为Gbit/s。而60GHz毫米波无线通信系统拥有着许多优势，比如在短距离范围内极高的组网密度和传输速率；利用极大的氧气衰减来降低临近小区干扰；附近大约7GHz的免费带宽等，60GHz无线通信凭借自身的潜力成为了现在许多研究者的研究目标。
本文主要研究了60GHz通信系统中单载波模式下的基带通信系统的仿真，首先对其理论原理进行相关的学习，包括系统的组成结构，主要包括发射部分的信源的产生，编码调制，并串变换；信道部分的多径衰落信道以及高斯白噪声信道；接收端的串并变换，解码解调以及频域均衡。研究了传输过程中的优势和不足。在熟悉了系统的原理后使用MATLAB软件来对其进行仿真，对系统采用了编程仿真。该系统对于传输速率为Gbit/s的通信系统的研究具有重要意义。 [资料来源：Doc163.com]

Abstract
With the advancement of science and technology, today's world is already evolving toward the information age. Human life cannot be separated from the transmission of information. However, the drift of communication systems over time is constantly changing. For example, the mobile phones we used, the former 1G, 2G, and 3G, have now become faster 4G. Although the communication system has brought great convenience to human life, people have higher requirements for it with the development of the times. The study of the transmission rate has progressed from the initial Kbit/s to Mbit/s, but it has now become Gbit/s. The 60GHz millimeter-wave wireless communication system has many advantages, such as extremely high network density and transmission rate in a short distance range; using of great oxygen attenuation to reduce the interference of nearby cells; free bandwidth around 7GHz, etc. 60GHz wireless Communication has become the research goal of many researchers today with its own potential.

This paper mainly studies the simulation of the baseband communication system in the single carrier mode in 60GHz communication system. First of all, it analyzes its theoretical principle, including the system's structure, which mainly includes the generation of the source of the transmitting part, coding modulation and serial-to-parallel transformation. Multi-path fading channel and Gaussian white noise channel are in the channel part. Parallel-to-serial conversion, decoding, demodulation, and frequency domain equalizationt are at the receiver. It researched transmission advantages and deficiencies. After familiarizing with the principle of the system, it was simulated using MATLAB software, and the system was programmed and simulated. This system is of great significance for the research of communication systems with a transmission rate of Gbit/s.
Keywords: 60GHz; single carrier mode; MATLAB; baseband communication system
