Design And Mplementaion Of A DSP-Based MIMO-LTE-A System

With the rapid development of modern telecommuication, people have more requirements for wireless telecommunication. From voice communicaiton to ever increasing requirement of data and video communication, time has posed new challenges for telecommuication technology.With the coming of3G,4G is not yet far from us.4G tech will improve system volume which will meet people’s increasing requirement. As a prior standard of4G, LTE-A is a new standard evolved through LTE and will become a prior technology for commercial. This thesis is based on a project cooperated by BUPT and Fujisu China Institute aiming to build a wireless communication platform of MIMO-LTE-A system.The platform shall reach a maximum transmission speed of300Mbps with8TX antenna at most. Meanwhile, the project will authenticate the critical techology in PHY layer.This thesis is focused on the baseband of system.We picked the C66x series DSP platform provided by TI and finally connect TX baseband with RX under a maximum speed of300Mbps. The thesis first makes known the design requirement, and accordingly. give out a blueprint for system. And then, we introduce our platform we are developing on, which consists both software and hardware platforms. After that, we show how the transmitter and receiver are designed and developed.Finally we conclude the thesis and set a goal for future. The thesis has many new tries on various aspects. Firstly, we realized the high speed transmission and data process based on LTE system. What comes next, we had a new vision on high-performance DSP and manage to develope them. And also, we have tested the algorithms on PHY layer. The project has a practical intention.
