将doubly stochastic matrix分解成一个排列矩阵的集合，并构造其概率分布(The doubly stochastic matrix is ​ ​ decomposed into a set of permutation matrix，at the same time，its probability distribution is constructed.)

Recently, Long Term Evolution (LTE) has developed a femtocell for indoor coverage extension. However, interference problem between the femtocell and the macrocell should be solved in advance. In this code, I propose an interference management scheme in the LTE femtocell systems using Fractional Frequency Reuse (FFR). Under the macrocell allocating frequency band by the FFR, the femtocell chooses sub-bands which are not used in the macrocell sub-area to avoid interference. Simulation results show that proposed scheme enhances total/edge throughputs and reduces the outage probability in overall network, especially for the cell edge users.
