Abstract

In this work, we investigate cooperative multihop communications based on OFDMA and fountain codes. Data packets are forwarded between clusters of simultaneously transmitting nodes which exploit the diversity of links by sharing the available subcarriers based on local channel conditions. Furthermore, to enable distributed MISO transmissions between clusters, we investigate the potential of distributing data packets within the cluster by single node transmissions prior to the common transmissions aiming to increase the achievable throughput. We present two novel forwarding schemes that utilize distributed MISO transmissions while taking advantage of the properties of fountain codes. The first scheme relies on a full distribution of all data packets within each cluster while the second scheme adapts the extent to which data packets are distributed within the cluster according to local channel conditions. The proposed schemes are compared to an exclusive SISO forwarding scheme in which no additional distribution within each cluster is used.

OFDMA多跳网络中基于分布式MISO的协同转发
本文研究了基于OFDMA和喷泉码的合作多跳通信。数据包在同时传输的节点群之间转发,这些节点利用链路的多样性,根据本地信道条件共享可用的子载波。此外,为了实现集群之间的分布式MISO传输,我们研究了在集群内通过单节点传输分发数据包的可能性,该传输先于共同传输,旨在提高可实现的吞吐量。我们提出了两种利用分布式MISO传输的新型转发方案,同时利用了喷泉码的特性。第一种方案依赖于每个集群内所有数据包的完整分布,而第二种方案根据本地信道条件调整数据包在集群内分布的程度。将所提出的方案与排他的SISO转发方案进行比较,后者在每个集群中不使用额外的分发。
