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

这是在非正交（NOMA）环境下对用户的功率分配采用固定分配，前后用户功率比满足一定的要求-This is at a non-orthogonal (NOMA) environment on the user' s power allocation fixed allocation before and after the user power ratio meet certain requirements
