尽管有潜力提高无线通信系统的性能，但基于中继的通信系统面临着巨大的挑战，资源浪费。在本文中，我们讨论了中继系统中的资源效率，特别是在利用多天线和改进双工以提高系统效率的双向和全双工中继系统中。我们详细比较了twr和fdr的特点、框架结构、性能、优缺点以及相关的技术挑战。通过量化性能的实例，我们证明了这两种方法都可以有效地减少基于中继的通信系统中的资源浪费。
In spite of their potential to improve the performance of wireless communication systems, relay-based communication systems face significant challenges, resource wastage. In this article we discuss resource efficiency in relay systems, particularly in two-way and full-duplex relay systems that utilize multiple antennas and improved duplexing to enhance system efficiency. We compare in detail the features, frame structures, performances, advantages and disadvantages, and technical challenges associated with TWRs and FDRs. Using illustrations of quantitative performance, we demonstrate that both of these approaches can efficiently reduce resource wastage in relay-based communication systems.
