Abstract :
The degrees of freedom of a cellular system in a fading environment are determined. An arbitrary number of base stations with multiple antennas and an arbitrary, but similar per cell, number of users with multiple antennas is considered. Two distributed algorithms which possibly achieve interference alignment are presented. Simulations show that the proposed algorithms achieve the optimal degrees of freedom.
