RF Transceiver System Research And Implementation For Next-generation Wireless Communication

Communication system has experienced the development of three generations of mobile communication system and now the large-scale network construction is the third generation of mobile communication system. 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. RF transceiver 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. RF transceiver determines the distance of communication and affects the communication s quality. The development of communication system has also led to the development of the RF transceiver. Although the third generation mobile communication provides mobile multimedia services, the speed and quality of communication has room for improvement. Now the fourth-generation mobile communication s technology is developing in many countries which use the new technology set a higher request to the radio frequency front end.The paper introduced mobile communication's development, each generation of mobile communication technology and the key technologies. Then it has discussed transceiver's basic structure and radio frequency transceiver's development and some key indicators. Because the specification of 4G has not yet determined, therefore according to the 3G target forecast the technical specification of 4G. Firstly the paper introduced the 4G radio frequency advanced concept technology demonstration system's structure and the main component's important target. Secondly according to these components's important target, it has calculated the radio frequency system's major technique target. Finally it simulated entire transceiver's major technique target. The thesis has tested overall system's some key parameters, viewing system's key property. The conclusion indicated that the entire transceiver can complete the function of receiving and the transmitting of basic 4G radio frequency.
