基于NOMA的功率分配，采用树形算法，根据不同用户的信噪比大小，一定的约束关系，分配功率-NOMA power allocation based on the use of tree algorithm, depending on the size of the user' s SNR, certain constraints, power distribution

martlab应用来确定某些参数来减少原材料体积而满足用户定义的约束。-martlab be used to identify certain parameters to reduce the volume of raw materials and meet user-defined constraints.
