基于无线通信射频收发机系统的设计

题目：基于无线通信射频收发机系统的设计基于无线通信射频收发机系统的设计摘 要近年来，射频(RF)无线通信技术的迅速发展增加了人们对低电压高性能射频前端的需求，无线通讯系统中的关键模块-RFIC 成为当前的研究热点，例如：蜂窝式个人通信与基站、无线接入系统、卫星通信、全球卫星定位系统、无线局域网等。经过三代移动通信的发展，通信系统发展成了支持多媒体的通信系统，系统的速度更快，误码率更低。射频收发机是通信系统的前端部分，负责信号的接收和发射部分，是无线通信系统中不可缺少的一部分，它决定了通信距离和影响着通信质量通信系统的发展也带动了射频收发机的发展。本文主要完成了基于移动通信的射频收发机系统，所做的工作可分为射频系统的指标分解、计算，前期的器件调研和选型，射频系统方案的设计和搭建，并进行 ADS的系统仿真。最后经过测试，其收发机的性能指标基本满足要求。关键词：移动通信；射频收发机；系统指标RF transceiver system design based on wireless communicationAbstractIn recent years ， the rapid development of radio frequency (RF) wireless communication increase the RF front-end needs of low-voltage and high-performance.The key modules-RFIC of Wireless communication systems become research focus,such as cellular personal communications and base station, wireless access systems, Satellite Communications,GPS, wireless lan,etc. After the development of three generations of mobile communications, communications system developed into a multimedia communication system and the system has faster rate and lower BER. RFtransceiver which is front of the communication system is responsible for receiving and transmitting the signal part and that is an integral part the wireless communication system has also led to thedevelopment of the RF transceiver. The paper discussed transceiver's basic structure and radio frequency transceiver's development and some key indicators. Then according to these important target, it has calculated the radio frequency system's major...
