Abstract


Completely independent intellectual property rights of the 3G standard , TD-SCDMA as China has gained widespread attention in the world , play a crucial role in promoting development in the China Mobile Communications Business . With the rapid development of communication technology applications , user data rates and quality of service requirements with the increasing promote TD-SCDMA must accelerate the evolution of speed in order to meet the increasing demand for data transfer rate . And existing mature technology used in 3G systems in order to improve the system performance of 3G , 3GPP organization research and standardization of LTE. As the line of succession to the TD-SCDMA TD-LTE TDD features , so as the the inevitable evolutionary direction for the future of TD-SCDMA . This paper describes the development of next-generation mobile communications technology trends ; LTE physical layer protocol , physical layer uplink and downlink shared channel and control channel protocol design ; TDD system -specific frame structure , and based on research realization of the HARQ . Using MATLAB software to build a physical downlink shared channel link level simulation platform ; research LTE downlink MIMO technology algorithm , and through simulation . TDD uplink and downlink channel symmetry , this paper presents a the LTE system validation symmetry process .
