摘　　要：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。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.
