[Abstract]:At present, LTE has been widely used all over the world. At the same time, the development of LTE technology, the evolution and standardization of related technology has not stopped. From time to time there are new algorithms, new technologies are proposed or written into the standard. In the process of technology research, more convenient, more economical, closer to the real system simulation platform is needed to verify the feasibility and practical effect of the technology. The core of this thesis is to design and implement a LTE physical layer simulation platform. The platform uses software radio technology, based on the key technology of LTE physical layer, to provide a flexible and economical new algorithm that may be used in the evolution of LTE to the next generation wireless communication system. Practical software simulation and hardware verification platform. This paper first introduces the software and hardware development environment of the simulation platform, then describes the overall design of the LTE physical layer simulation platform, including the system architecture, performance parameters and so on, and analyzes some important theories and algorithms involved in the simulation platform. For example, orthogonal Frequency Division Multiplexing (OFDM), multiple input / multiple output (MIMO), synchronization, Channel estimation, Channel Equalization, etc. Then, the detailed implementation of the simulation platform, including how to transmit and receive RF signals, is described in detail. How to realize all kinds of algorithms by software. Finally, the performance testing process of the completed simulation platform is described, and the test contents, test methods and test results are explained, and the test results show that the designed simulation platform can meet the requirements of the design.
