In this paper, the transmission performance considering an error of channel state information (CSI) feedback for a downlink mobile WiMAX system with multiuser multiple-input multiple-output (MU-MIMO) systems in a computer simulation and field experiment are described. In computer simulation, a downlink MU-MIMO system can be realized by using the block diagonalization algorithm, and each user can receive...
In this paper, a routing method for Wi-Fi mesh networks considering traffic load balancing and quality of service (QoS) is proposed. A mesh network is constructed with several static access points, and each access point connects each together with Wi-Fi technology. Wireless mesh links between access points are established by using proposed routing method which is based on the optimized link state...
