RA准则下的OFDM自适应资源分配问题，涉及载波和功率的分配，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。(RA OFDM under guideline adaptive resource allocation problem, involving carrier and power allocation is a decision with both a discrete variable, but also with continuous decision variables of nonlinear optimization models, and contains more complex nonlinear constraints, so for using intelligent optimization algorithm.)

解决了连续马尔科夫模型训练、观测向量概率计算、输出参数估计问题，需安装HMM工具包(CHMM model,trianing and estimation)
