-This paper investigates the diversity gain offered by implementing network coding [1] over wireless communication links. The network coding algorithm is applied to both a wireless network containing a distributed antenna system (DAS) as well as one that supports user cooperation between users. The results show that DAS with network coding leads to better diversity performance, at a lower hardware cost and higher spectral efficiency. In the case of user cooperation, network coding yields additional diversity, especially when there are multiple network users.

“…Distributed antenna system (DAS) has been originally implemented to cover dead spots in indoor wireless communications and then used to maximize cell coverage in cellular networks [9]- [12]. This setting has recently gained a great deal of interest as a promising potential to satisfy fast-growing demands for next generation wireless systems because of its power savings and capacity merit over conventional colocated antenna system (CAS) [13]- [18].…”

Abstract-Distributed multiple-input multiple-output (D-MIMO) is a promising technique for next generation wireless networks, which offers a remarkable spectral efficiency gain over the conventional co-located MIMO (C-MIMO). In contrast to C-MIMO, which can be regarded as a special case of D-MIMO, performance analysis of D-MIMO is a challenging problem. This is because radio channels between a user and the distributed radio ports (RPs) are characterized by non-identical path-loss and shadowing effects which render the classical analytical methods non-tractable. In this paper, new accurate expressions for the uplink spectral efficiency of D-MIMO and C-MIMO systems are presented and compared for given large-scale coefficients. We further consider the uplink spectral efficiency for a single-cell distributed large-scale MIMO (D-LMIMO) system with linear zero-forcing (ZF) receivers, accounting for path loss along with shadow fading and multi-path fading effects. Exact expressions for the average spectral efficiency over shadow fading in the asymptotically very large number of RPs antennas regime is explicitly derived, and a tight closed-form lower bound on the asymptotic spectral efficiency is presented. We demonstrate that, the transmit power of each user in D-LMIMO can be scaled down proportionally to the inverse of the number of RP antennas with no performance reduction. Moreover, we study the spectral efficiency of a D-MIMO in a multi-cell environment taking into account accurate co-channel interference (CCI) models. These expressions provide meaningful insights into the impact of SNR, RPs and user positions, number of RPs antennas, shadow fading, and out-of-cell interference on the spectral efficiency of D-MIMO over practical scenarios. Finally, numerical results are validated by simulation to confirm our analysis.Index Terms-Distributed antenna system (DAS), multipleinput multiple-output (MIMO) systems, large-scale MIMO (L-MIMO), spectral efficiency, zero-forcing (ZF) receiver, co-channel interference (CCI).
