Model and comparative analysis of reduced-complexity receiver designs for the LTE-advanced SC-FDMA uplink
Due to its favorable peak-to-average power ratio (PAPR), a single-carrier frequency-division multiple access (SC-FDMA) scheme has been chosen for the 3GPP Long Term Evolution Advanced (LTE-A) uplink, as opposed to the orthogonal frequency-division multiple access (OFDMA) scheme used in the downlink. SC-FDMA, however, is prone to suffer from the effects of inter-symbol interference. When combine...
متن کاملComplexity Reduced MIMO Interleaved SC-FDMA Receiver with Iterative Detection
In this paper, we propose the receiver structure for Multiple Input Multiple Output (MIMO) Interleaved Single Carrier-Frequency Division Multiple Access (SC-FDMA) where the Frequency Domain Equalization (FDE) is firstly done for obtaining the tentative decision results and secondly using them the Inter-Symbol Interference (ISI) is cancelled by ISI canceller and then the Maximum Likelihood Detec...
متن کاملEnergy 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 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 کاملTomlinson Harashima Precoding for SC-FDMA
There is considerable interest in the use of Single Carrier Frequency Division Multiple Access (SC-FDMA) as the uplink transmission scheme in the 3GPP Long Term Evolution standard. In this paper a pre-DFT time-domain implementation of Tomlinson-Harashima Precoding (THP) for uplink SC-FDMA is proposed. We demonstrate how precoding the uplink transmission is an alternative signal processing techn...
