A new method for optimizing the power allocation in a communications system that can be decomposed in multiple parallel channels have been developed and patented. The technology allows to optimize the transmission rate, power or energy efficiency of a communications system with very low complexity. Partners to further develop the system and/or to establish commercial agreements along with technical cooperation are sought.
The Challenge
is to obtain a very simple solution,
The Technology
This present technique enables the computation of the optimal power allocation with a complexity 2 to 3 orders of magnitude lower than related techniques.
The method uses ordered statistics to pre-compute offline a set of look-up tables based on the channel statistics. As new users enter or leave the system or the channel parameters change, the optimal power allocation is obtained from the look-up table with negligible complexity.
