Abstract

In this work, we propose and analyze a construction of adaptive network codes for a multiple access network under independent block-fading assumption. We aim to increase the system average transmission rate of the recently proposed generalized dynamic-network codes (GDNC) without reducing its diversity order, making use of a small amount of information fed back by the base station. The average rate and the diversity order are obtained analytically, and computer simulations of the diversity order are shown to agree with the analytical results.
