- Abstract
- We develop the optimal transmit power allocation
scheme that maximizes the total throughput for a downlink twouser
interference channel. The derived optimal scheme allocates
the total power to one user in better channel state, as in the
greedy scheme, when the degree of interference between users
exceeds a certain threshold. When it is less than the threshold, on
the contrary, the transmit power is divided into two users, as in
the water-filling scheme. Numerical results are presented to verify
the optimality of the derived scheme and to show throughput
gains over the greedy and water-filling schemes.
