Small cell enchantment is emerging as the key technique for wireless network evolution. One challenging problem for small cell enhancement is how to achieve high data rate with as-low-as-possible control and computation overheads. As a solution, we p

Interference nulling (IN) is a linear precoding tech-nique for downlink multiuser multiple-input multiple-output(MU-MIMO) systems. With perfect channel knowledge at the transmitter, IN eliminates other users' interference at each cell, thus improving
