Multihop transmission is deemed as one possible solution to improve transmit rate and extend coverage of wireless cellular networks. In this paper, full reuse resource partition schemes for multihop cellular networks (more than two hops) are exploited by graph methods to achieve efficient resource utilization. Two types of network topologies are considered, i.e. tree and mesh structures. Simulation...
Recently there has been an upsurge of interests in the multihop infrastructures for orthogonal frequency division multiplexing-based cellular networks in both academia and industry. In this article, we first present an overview of the interference coordination strategies in OFDM-based multihop cellular networks. Then, based on the framework of third-generation LTE-Advanced networks with multihop relaying,...
In this paper, a distributed power control algorithm is proposed to perform adaptive spatial multiplexing for the relay enhanced orthogonal frequency division multiple access (OFDMA) cellular systems. As the optimal spatial multiplexing problem is non-convex, we utilize the distributed iteration method to achieve its near-optimal solution. By determining the restriction on the transmit power for each...
