Bi-directional link multiplexing for MIMO mesh network

In this paper, an architecture of MIMO mesh network which avoids co-channel interference and supplies link multiplexing simultaneously is considered. In particular, this paper considers the multi-hop relaying case with bi-directional transmission. As a MIMO transmission scheme, nonlinear algorithm based on dirty paper coding and successive interference cancellation is developed for the proposed MIMO mesh network. In this paper, the performance of the MIMO mesh network in LOS environment is evaluated. As a result, the MIMO mesh network is superior to the conventional MIMO mesh network in LOS environment as well as NLOS environment.
