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 ...

Analog SC-FDE using single sideband technique
2014 International Conference on Advanced Technologies for Communications (ATC 2014), 2014In order to improve performance of analog signal transmission, we recently proposed a novel analog single-carrier transmission with frequency-domain equalization (analog SC-FDE). Analog SC-FDE adopts double sideband (DSB) technique (referred to as analog SC-DSB-FDE) to transmit signal. In this paper, in order to double the spectrum efficiency of analog

Receiver structures for MIMO-SC/FDE Systems
2006 IEEE 63rd Vehicular Technology Conference, 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

Channel Estimation Schemes for SC-FDE/FS System
11th IEEE Symposium on Computers and Communications (ISCC'06), 2006Single carrier with frequency domain equalization (SC-FDE) utilizing channel state information (CSI) has been proposed in [1]. This paper discusses the channel estimation schemes for that system, especially in timevariant environments. Some simulations are shown under IEEE 802.11a [2] and IEEE 802.16 [3] scenarios.

A Timing Synchronization Scheme for SC-FDE System
2007 International Conference on Wireless Communications, Networking and Mobile Computing, 2007The SC-FDE(single carrier-frequency domain equalizer) is a field that gathers more and more interest as a modulation scheme for the broadband wireless communications, for simple channel equalization ,SC-FDE systems perform equalization in frequency domain instead of time-domain using FFT, IFFT and CP (cyclic prefix) like it user for example in OFDM ...

SC/FDE, OFDM and CDMA: A Simplified Approach
2006 European Conference on Wireless Technologies, 2006We apply code division multiple access CDMA to single carrier transmission with frequency domain equalization SCFDE. We use the Fourier spreading codes at the transmitter with length equal the number of users and across the active users. It leads to the cancellation of the despreading process together with the inverse fast Fourier transformation (IFFT)

Coded SC-FDE system over impulsive noise channels
IET Conference on Wireless, Mobile and Sensor Networks 2007 (CCWMSN07), 2007Single carrier transmission with cyclic prefix (SC-CP or SC-FDE), has lower PAPR (peak to average power ratio) problem and requires smaller backoff of amplifier than orthogonal frequency division multiplexing (OFDM) technique. In order to combat impulsive noise under power limited channels, we apply regular LDPC (low density parity check) codes and ...

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 ...

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).
