PROJECT TITLE :

Exact Assessment of the Delay-Rate Tradeoff in Ergodic Interference Alignment - 2018

ABSTRACT:

So as to increase the network capability and fulfill the quality of Service needs in multi-user wireless networks, interference alignment (IA) has been proposed. Subsequently, ergodic IA was introduced as a promising theme to attain a degrees-of-freedom metric equal to (one/2), at the expense of additional delay. During this letter, we tend to study the delay-rate trade-off in ergodic IA and specifically compute the best delay exponent of JAP-B, the state-of-the-art ergodic IA scheme. Moreover, we derive lower and higher bounds for the best delay exponent and show the a lot of better tightness of the proposed bounds compared with those accessible in the state of the art.
