Considering the quality-of-service (QoS), power allocation is a critical importance issue in realizing multi-hop relay systems. In this paper considering the QoS Constraints in term of BER or instantaneous SNR, an optimal power allocation scheme that minimized the total power consumption in an amplify-and-forward (AF) multi-hop multi-branch transmission(More)
Device-to-Device (D2D) communication is one of the new features introduced for Long Term Evolution-Advanced (LTE-A) and beyond networks. In this paper we address the problem of communication mode selection for a pair of User Equipments (UEs). In particular we assume that the paired UEs can choose from the reuse, dedicated, and cellular modes. While this(More)
Device-to-Device (D2D) transmission is a promising technology which enables the User Equipments (UE) in 5G cellular networks to directly communicate without going through the evolved Node-B (eNB). In such networks UEs should select a Transmission Mode (TM) amongst reuse, dedicated, and cellular modes by maximizing the overall transmission throughput or(More)
This paper presents a decentralized model predictive based load frequency control for multi-area power systems. An MPC controller is designed for each area to decrease the effect of load disturbances and parameter uncertainties owing to variations in power system’s parameters. Also to estimate load changes, Fast Output Sampling (FOS) method is used. The(More)
Blind detection of communication parameters are one of the main areas of research in urban and military communications. Among these studies many contributions have been devoted to extracting the parameters of block and convolutional codes, assuming the type of code is known. To achieve these purposes the type of the applied code should be specified before.(More)
