Abstract
A telecommunication network component, comprising: a memory configured to store instructions, and a processor configured to execute the stored instructions, the instructions comprising: determining a plurality of power allocation adjustments for signals transmitted via an antenna array that promotes decision-feedback detection without using channel state information, and outputting the power allocation adjustments to the array. Also disclosed is a power allocation method comprising: determining a power allocation scheme that promotes decision-feedback detection in a multiple-input and multiple-output system without using channel state information, and implementing the power allocation scheme on an antenna array by modifying an adjustment for each of a plurality of antennas in the array.
