The Implemention Of Sending And Recieving Lte Pucch And Srs Based On GPP

As a long-term evolution of UMTS (Universal Mobile Telecommunication System),LTE is started by3GPP.Through the use of new technoloy of OFDM and MIMO,LTE system can reach a peak rate50MBPS in uplink and a peak rate of100MBPS in downlink.The PUCCH channel ensure the controlling signal of LTE uplink system and the SRS used for uplink channel quality measurement,both played an an essential part in LTE system.At the same time,the rapid development of GPP latest years meet the requirement of f eal-time signal processing.As a result,the research of PUCCH and SRS is the target of this article.The main work of this paper is to realize the sending and receiving of PUCCH and SRS on Intel GPP.In the first place the key technology of LTE system is introduced, then do research on the structure of PUCCH and the theory of SRS.Then introduces the development platform and development tools and the optimization idea. Next build MIMO fading channel of li-huang model on MATLAB simulation platform to simulate several different channel cases of PUCCH format1a and format2, compared the performance data with the3GPP protocol, to ensure that the feasibility of the algorithm design.Then sending and receiving of PUCCH and the generating and receiving of SRS on Intel GPP.Then detailed introduced the concrete implementations of key modules of PUCCH and SRS include the optimizing of PUCCH and SRS using SSE or some other method. At the end of the paper, performance optimization schemes and methods are concluded.The design architecture, implementation and optimization were proved effective and efficient for LTE uplink receiver with lower latency and preferable performance.
