Energy efficient QoS constrained scheduler for SC-FDMA uplink
In this paper we propose a framework for an energy efficient scheduler for multiuser SCFDMAwith queue state information (QSI) and quality of service (QoS) constraints. Resource allocation is formulated as a two-stage problemwhere resources are allocated in both time and frequency. The scheduling policy is obtained in two stages for the intraand inter-user allocations respectively. A near optima...
متن کاملQoS-Constrained Resource Allocation Scheduling for Uplink SC-FDMA
Long Term Evolution (LTE) is the most promising technology for 4G mobile communication networks. The goal of LTE is to provide high data transmission rate, scalable bandwidth, low latency, and high-mobility. LTE employs Orthogonal Frequency Division Multiplexing (OFDM) and Single Carrier Frequency Division Multiple Access (SC-FDMA) for downlink and uplink data transmission, respectively. As to ...
متن کاملPARAFAC-based frequency synchronization for SC-FDMA uplink transmissions
Frequency synchronization is a critical requirement for single-carrier frequency division multiple-access (SC-FDMA) uplink transmissions. Based on the key observation that the received signal at the base station can be formulated as the parallel factor analysis model, we present a joint carrier frequency offset (CFO) estimation and compensation scheme for SC-FDMA uplink transmissions with inter...
متن کاملAdaptive equalisation using particle swarm optimisation for uplink SC-FDMA
Techset Com An adaptive frequency-domain equaliser for the single carrier frequency division multiple access (SC-FDMA) system using the particle swarm optimisation (PSO) technique is proposed. Unlike the stochastic gradient and recursive least squares algorithms, the PSO is known to have fast convergence which does not depend on the underlying structure. The cost function used in a PSO is formu...
متن کاملLow Complexity CFO Compensation Scheme for SC-FDMA Uplink System
Single Carrier Frequency Division Multiple Access (SC-FDMA) has been adopted for fourth generation (4G) mobile uplink transmission schemes because of its low Peak to Average Power Ratio (PAPR) as compared to that of Orthogonal Frequency-Division Multiple Access (OFDMA).Since SC-FDMA has low PAPR, it is sensitive to Carrier Frequency Offsets (CFOs) similar to that of OFDMA. To minimize and compe...
