In this paper, we propose a simplified approach for the Mixed Integer Non-linear Programming (MINLP) problem in the context of dynamic resource allocation for multiuser downlink Orthogonal Frequency Division Multiplexing (OFDM) systems. Our solution is based on the appropriate selection of the K-best branches of the branch and bound technique. The proposed algorithm significantly decreases the computational...
In this paper, we consider an LTE downlink Multiple Input Multiple Output (MIMO) Coordinated Multipoint (CoMP) network. We propose a new adaptive precoding method applied on the signals being transmitted by the set of active antennas. Based on Joint Processing (JP) technique and the precoding method, we define a joint cellular area of cooperation between different evolved NodeBs (eNodeBs) serving...
In this paper, we propose a novel positioning algorithm based on hybrid cooperative techniques. The proposed algorithm is divided into two main categories: initial positioning and tracking. After acquiring an estimate about the distances of an un-located mobile terminal (UMT) by measuring the Received Signal Strength (RSS) and Time of Arrival (ToA), we obtain initial position for an UMT via triangulations...
