我们开发了两种能量高效的协作分集协议来对抗无线网络中多径传播引起的衰落，其底层技术建立在经典的中继信道和相关工作的基础上，并通过协作无线电的协调传输和处理来利用分布式天线上可用的空间分集。虽然适用于任何无线设置，但这些协议在ad-hoc或对等无线网络中尤其有吸引力，在这些网络中，无线电通常被限制为使用单个天线。由这些协议产生的大量节能可以导致减少电池消耗、更长的网络寿命以及改善例如容量方面的网络性能。
We develop two variants of an energy-efficient cooperative diversity protocol that combats fading induced by multipath propagation in wireless networks, The underlying techniques build upon the classical relay channel and related work and exploit space diversity available at distributed antennas through coordinated transmission and processing by cooperating radios. While applicable to any wireless setting, these protocols are particularly attractive in ad-hoc or peer-to-peer wireless networks, in which radios are typically constrained to employ a single antenna. Substantial energy-savings resulting from these protocols can lead to reduced battery drain, longer network lifetime, and improved network performance in terms of, e.g., capacity.
