Linear interference alignment based on signal and interference space ranks
In this paper, we discuss the implementation problem of interference alignment with low complexity. Firstly, interference system model based on signal and interference space is analyzed. Then, the design of chordal distance based linear precoder and receiver filter based on the optimization problem of rank of interference space are presented. Simulation results confirm that the sum rate of linear interference alignment is close to the iterative alignment scheme, but the computation complexity can be reduced greatly.
