Self-organizing network is used for regional communications, which makes up for the coverage of mobile communication system. In LTE-Advanced network, such network forms by proximity communications and utilizes the limited bandwidth efficiently. However, the system frequencies shared by the terminals in self-organizing network belong to cellular terminals, the resource reusing leads to interference...
In Release 10 of TD-LTE-Advanced standard, the technique of relay is introduced to extend the network coverage, improve the cell-edge performance and increase the fairness among users. Resource allocation is an important issue in relay-enhanced TD-LTE-Advanced system, and in this paper, a downlink resource allocation algorithm considering direct link, backhaul link and access link is proposed. The...
The combined Block Digonalization precoding and Geometric Mean Decomposition (BD-GMD) scheme is developed to eliminate the multiuser interference and improve the system performance of bit error rate (BER) in the multiuser multiple input multiple output (MU-MIMO) systems. For the resource allocation and scheduling of BD-GMD system, the equal power allocation and water-filling algorithm for the impact...
In this paper, an effective joint allocation of power and subcarriers is proposed under the total power constraint, aiming to maximize the capacity of OFDMA relaying network. In DF (decode and forward) scheme, an equivalent transmit rate formulation is developed, optimal power allocation is obtained by linear optimization and Lagrange multiplier method. By using this optimal power allocation, an efficient...
