摘要
本文研究了LTE系统中基于码本选择的预编码发送方案,对LTE基于码本选择的预编码方案进行了推导,提出了基于性干比(SINR)的码本选择算法,并对其进行了性能仿真。仿真结果表明,在4根发射天线和2根接收天线配置下,基于码本的预编码简单实用,且能够在在满足LTE性能需求的基础上大大提高系统性能。
Conduct research on the precoding for codebook selection in LTE.Precoding for codebook selection in LTE were analysed and the algorithm of codebook selection based on SINR had been concluded.Simulations had been conducted in a comparable manner.Results show that the performance of precoding with 4Tx and 2Rx is better than unprecoding,and the algorithm of codebook of SINR is reliable and it can meet the requirements of LTE.
