However, the current study was based on a given power; it does not take full advantage of the system's total power. How to allocate power among the users based on interference alignment is the key to this paper. Firstly, a framework of MIMO interference channel was developed and subspace interference alignment was analyzed. Secondly, a novel interference alignment scheme based on dynamic power allocation that can fully use of system power was proposed. Finally, a performance simulation in LTE system was present. The result shows that the average BER and interference power have a significant improvement at the expense of only a tiny system capacity.Read More
