我们研究了一种具有一对源-目的地和多个中继的无线网络,这些中继以多跳方式将数据从源转发到捐赠。我们比较两种方案:i) 中继在放大转发 (AF) 模式下运行,并在源和目标之间建立点对点 MIMO 通道(MIMO 隧道),ii) 中继在解码转发 (DF) 模式下运行,数据在不同的网络路径上传输(多路径传输)。我们表明,在信息速率方面,采用 AF 中继的 MIMO 隧道优于采用 DF 中继的多路径传输。
We study a wireless network with one source-destination pair and several relays that forward the data from source to donation in a multi-hop fashion. We compare two schemes: i) The relays operate in an amplify-and-forward (AF) mode and establish a point-to-point MIMO channel between source and destination (MIMO tunnel), ii) The relays operate in a decode-and-forward (DF) mode and the data Is transmitted over different network paths (multi-path transmission). We show that the MIMO tunnel with AF relays outperform the multipath transmission with DF relays with respect to information rates.
