We consider the problem of maximizing sum rate on a multiple-antenna downlink in which the base station and receivers have multiple-antennas. The optimum scheme for this system was recently found to ...

Multiplying Using a Sum in Oracle. The "Sum" function in Oracle allows you to add up all data from a specified column and displays a result in your query results. You can use the multiple feature ...

In this paper, we consider the problem of power control for sum-rate maximization on multiple interfering links [transmitter-receiver pairs (Tx-RX)] under a sum power constraint. We consider a ...
