OFDM自适应资源分配问题（载波、功率等），是一个既含有离散决策变量，又含有连续决策变量的非线性优化模型，且含有较为复杂的非线性约束，因此适合采用智能优化算法进行求解。本源码由GreenSim团队原创，转载请注明，有意购买源码或代写相关程序，请与GreenSim团队联系 -OFDM adaptive resource allocation problem (carrier power), is a both a discrete decision variables, but also co

Channel estimation techniques for OFDM systems based on a pilot arrangement are investigated. Channel estimation based on a comb type pilot arrangement is studied through different algorithms for both estimating the channel at pilot frequencies and i
