摘要
以导频总功率最小化为准则,提出了一种适用非连续正交频分复用系统的导频设计方法。与传统的子载波总功率受限的导频设计方法相比,对给定的导频辅助信道估计最小均方误差指标,需要较小的导频总功率,从而提高了数据传输的功率利用率,这也响应了当今社会提倡的节能减排的号召。仿真结果证明了该结论。
Based on minimum power of pilots,a method to design pilots for non-contiguous orthogonal frequency division multiplexing (NC-OFDM)system is proposed in this papers.Comparing with traditional method,it requires smaller power under the condition of the given MSE.Therefore it increases availability of power.This also responds the popular energy-saving and emission reduction.Simulation proves it correct.
