The problem of placing training symbols optimally for orthogonal frequency-division multiplexing (OFDM) and single-carrier systems is considered.
In optical transport networks, recent development of new technologies has led to highly accelerated ("disruptive") increases in the capacity associated with a given investment cost.
In this paper, we focus on the design of an optimal power allocation algorithm and an efficient user selection scheme for the downlink of a non-orthogonal multiple access (NOMA) system with power-d
Recently, the duality between multiple-input multiple-output (MIMO) multiple-access channels (MAC) and MIMO broadcast channels (BCs) has been established under a total power constraint.
In xDSL systems, in-domain crosstalk is easily dealt with based on zero-forcing receiver or precoding while out of domain or alien crosstalk requires a more advanced processing.
Small cell networks promise to boost the capacity and provide good QoS (Quality of Service) to cell edge users.
Resource Allocation (RA) in cellular networks is a challenging problem due to the demanding user requirements and limited network resources.
In this paper, we study a repeated moral hazard problem in which an agent is paid constant wage every period and retained on the job provided his past performance has met the following standard: he
We introduce new dual-polarization probing codes based on two frequency sweep signals enabling perfect estimation of the tested fiber backscattered optical field.
A time-constrained capital-budgeting problem arises when projects, which can contribute to achieving a desired target state before a specified deadline, arrive sequentially.
