Outage Performance of a Multiuser Distributed Antenna System in Underwater Acoustic Channels
نویسندگان
چکیده
The distributed antenna system (DAS) has been known for providing a large coverage and throughput in terrestrial radio environments. In this work, we investigate the benefits of DAS relative to the centralized antenna system (CAS) in underwater acoustic (UWA) environments. In particular, we analyze the outage performance in the wideband uplink transmissions. Based on theoretical derivation and numerical results, we show that at a medium transmission SNR regime, DAS outperforms CAS in both single-user and multiuser systems. To address the cochannel interference in the multiuser DAS, we suggest a multicell structure, which is shown having a lower outage error floor relative to the structure which takes the operation area as a single cell.

متن کاملProbabilistic analysis of system outage in distributed antenna systems with composite channels
Distributed antenna systems (DAS) play a key role in future wireless communications. Despite the increasing previous research work, the channel models of DAS lack generality. This paper presents a holistic and generic channel model, which incorporates path loss, lognormal shadowing, and generalized-gamma fast fading into consideration. This overarching composite channel model encompasses well-k...
