A TDMA scheme for SC-FDE UWB communications
GLOBECOM '05. IEEE Global Telecommunications Conference, 2005., 2005We propose a time division multiple access (TDMA) scheme for the BPSK modulated single carrier block transmission with frequency domain equalization (SC-FDE) over ultra-wideband (UWB) communications. The transmitter and receiver matrices for the proposed TDMA SC-FDE system are derived to achieve the multiple access interference (MAI) free and ...

Impact of Imperfect Channel Estimation on SC-FDE
2013 IEEE 77th Vehicular Technology Conference (VTC Spring), 2013Imperfect channel estimation can have a severe impact on the performance of coherent detection systems. In this paper we study the effect of imperfect channel knowledge in the performance of SC-FDE (Single Carrier with Frequency Domain Equalization).

On Interference in Uplink SDMA SC-FDE system
Fifth Annual Conference on Communication Networks and Services Research (CNSR '07), 2007In this paper, the issue of channel estimation with multiple in-cell co-channel users (ICUs) in the presence of out of cell interferers (OCIs) is addressed. A single carrier frequency domain equalization (SC-FDE), uplink space division multiple access (SDMA) system with iterative block decision feedback equalization (IBDFE), based on the soft decisions

Efficient receivers for SC-FDE with offset modulations
MILCOM 2012 - 2012 IEEE Military Communications Conference, 2012Offset QAM signals (Quadrature Amplitude Modulation) allow good power-bandwidth trade-offs, making them good candidates for broadband wireless systems, especially when combined with SC-FDE schemes (Single-Carrier with Frequency-Domain Equalization).

MIMO Extensions for SC/FDE Systems
The European Conference on Wireless Technology, 2005., 2006Several efforts are currently underway in investigating multiple-input multiple-output (MIMO) communication systems. MIMO technology promises high data rate wireless communications and/or the potentiality of exploiting transmit and receive diversity schemes. For WLAN (wireless local area networks) scenarios most investigations focus on OFDM (orthogonal

2006 International Conference on Wireless Communications, Networking and Mobile Computing, 2006
In this paper, we demonstrate that SC-FDE has different error characteristic from OFDM. Accordingly, we point out that both comparisons of coded BER between OFDM with block interleaving and SC-FDE in the classical literatures are unfair. And then, we propose a new coding scheme, which could take the advantage of the constraint of the coded information ...

A Blind Fine Synchronization Scheme for SC-FDE Systems
IEEE Transactions on Communications, 2014This work presents a blind fine synchronization scheme, which estimates and compensates residual carrier-frequency offset (RCFO) and symbol timing offset (STO) , for single-carrier frequency-domain equalization (SC-FDE) systems. Existing fine synchronization schemes for SC-FDE systems rely on time-domain unique words (UW) sequences as reference signals

A Novel Timing Synchronization Method for SC-FDE Systems
2008 International Symposium on Computer Science and Computational Technology, 2008In SC-FDE (single carrier with frequency domain equalization) systems, the factor which affects the performance of systems seriously is synchronization. Based on the studying of the algorithm of T.Schmidl & D.Cox and H.Minn, a novel timing synchronization method is proposed towards the SC-FDE systems in this paper.

Precoded MIMO-SC-FDE and blind channel estimation
APCCAS 2008 - 2008 IEEE Asia Pacific Conference on Circuits and Systems, 2008In multiple-input multiple-output (MIMO) communications systems, a crucial role is played by channel estimation as the accuracy of estimation will have a substantial effect on the overall system performance. In this paper we consider designing precoding matrices and blind channel estimation algorithms for MIMO single carrier with frequency domain ...

Subspace Decomposition for Channel Estimation in SC-FDE Systems
2013 IEEE 77th Vehicular Technology Conference (VTC Spring), 2013Single carrier frequency division multiple access (SC-FDMA), a multiple user access scheme based on the single carrier frequency domain equalization (SC-FDE) technique, has been proposed for the uplink in fourth generation (4G) mobile communications. SC- FDE requires reliable channel estimates to maintain an acceptable bit error rate (BER) performance.
