Abstract
In this paper, a low complexity dynamic resource
allocation algorithm is considered for the OFDMA based
downlink of 3GPP LTE. A maximal ratio weighted metric based
on the normalized channel gains of all users is proposed. The
novel low-complexity but sub-optimal allocation algorithm can
achieve a near optimal performance when used in combination
with this metric. To evaluate the performance of the proposed
algorithm and other resource allocation algorithms, a
computational complexity analysis is performed and a 1-bit
feedback scheme is employed in the performance analysis.
Simulated and theoretical results comparing the proposed
algorithm and other resource allocation algorithms are presented
for LTE.
