Data aggregation using doped turbo codes

Abstract

Modified data aggregation at MAC layer of 4G technology using dynamic aggregation technique, wherein the data from neighboring nodes is embedded in the turbo encoded payload of the selected node is proposed in this paper. This model developed on NS3 platform is compared to the existing AFR techniques and is found to have a lower encoded data bit rate. This scheme integrates aggregation & reliability (low bit error rate resulting from usage of Turbo codes) using the same basic architecture leading to a reduction in the power consumption. The proposed embedding scheme (of 1/3 rate) detailed in our paper results in a BER which is better than that of rate ½ turbo codes.
