Research On RF Uplink For TD-LTE Base Station

LTE(Long Term Evolution) has never be so compelling since it is proposed on the2004Toronto meeting of3GPP (The3rd Generation Partnership Project). Although the3G technique has not been spread widely, it does not affect the hot pursuit of the LTE.The TD-LTE is researched in this paper. The RF link of TD-LTE base station receiver is realized based on the3GPP technical specifications and requirements for TD-LTE. The RF system structure is investigated, using the introduction of base station system as the starting point.1) The zero-IF structure is chosen as the direction of this thesis after the comparison with several mainstream receiver structure.2) The general RF characteristics of LTE communication system and the special RF features of TD-LTE base station receiver are proposed by combining the related protocol of3GPP.3) The overall RF target of TD-LTE base station receiver is proposed quantitatively based on the specific analysis of RF characteristics. The RF target is implemented through distribute them into specific circuit function modules by using ADS2008link simulation control. The Chip Select ion and circuit design work is implemented using the calculated circuit RF target.4) The circuit board is designed. This thesis has always been based on theory research and analysis to guide engineering practice, and deepen the understanding and awareness of theory through engineering practice.
