基于 DFT 扩展广义多载波系统的信道估计方法研究

摘要

The study in this paper is based on DFT-Spread-Generalized Multi-Carrier system.According to the pilot sequence and time-frequency structure , it studies a maximum likelihood channel estimate algorithm that with low complexity and easy realization for uplink system .The algorithms are simulated , and the results are also presented in the paper .%基于DFT扩展广义多载波系统，根据导频序列和导频时、频结构，针对上行链路系统，研究低复杂度的、易于实现的时域最大似然信道估计算法，并对算法进行了仿真，给出了仿真结论。
