OPPORTUNISTIC INTERFERENCE ALIGNED USER SELECTION IN MULTIUSER MIMO INTERFERENCE CHANNELS

摘要

PURPOSE: An opportunistic interference alignment selecting method in multiuser MIMO interference channels is provided to drastically reduce calculation complexity. CONSTITUTION: At least one transmitter(101,102,103) broadcasts each random beam. A receiver of users feeds relations between interference channels back to at least one transmitter. At least one transmitter selects a user. The selected user forms a beam. A post processing vector of the selected user is calculated after the user is selected.
