Performance of Blind Turbo Equalizer in Indoor Channels

Journal of Communications Software and Systems, 2011
In this paper, we consider the transmission of turbo coded symbols in the indoor radio environment. The system isaffected by the intersymbol interference (ISI) caused by the multipath time-delay spread of the transmission medium.

Reduced Complexity I/Q Turbo Detection for Space-Time Trellis-Coded Systems

, 2004
A reduced-complexity turbo-detection scheme, referred to here as the R-TD arrangement, is proposed for employment in space-time trellis-coded (STTC) systems using the inphase/quadrature-phase (I/Q) cancellation technique that was previously developed for

Equalization of Sparse Intersymbol-Interference Channels Revisited

EURASIP Journal on Wireless Communications and Networking, 2006
Sparse intersymbol-interference (ISI) channels are encountered in a variety of communication systems, especially in high-data-rate systems. These channels have a large memory length, but only a small number of significant channel coefficients.

Interference Cancellation Schemes for Single-Carrier Block Transmission with Insufficient Cyclic Prefix

EURASIP Journal on Wireless Communications and Networking, 2008
This paper proposes intersymbol interference (ISI) and interblock interference (IBI) cancellation schemes at the transmitter and the receiver for the single-carrier block transmission with insufficient cyclic prefix (CP).

MAP Detection for Double-Layer Bit-Patterned Media Recording

Applied Sciences
The rapid increase in global data generation has intensified the demand for magnetic storage systems with substantially higher areal density. Double-layer bit-patterned media recording (DLBPMR), which integrates the benefits of bit-patterned media ...

Partial PIC-MRC Receiver Design for Single Carrier Block Transmission System over Multipath Fading Channels

International Journal of Antennas and Propagation, 2012
Single carrier block transmission (SCBT) system has become one of the most popular modulation systems due to its low peak-to-average power ratio (PAPR), and it is gradually considered to be used for uplink wireless communication systems. In this paper, a

Joint Effects of Synchronization Errors of OFDM Systems in Doubly-Selective Fading Channels

EURASIP Journal on Advances in Signal Processing, 2009
The majority of existing analyses on synchronization errors consider only partial synchronization error factors. In contrast, this work simultaneously analyzes joint effects of major synchronization errors, including the symbol time offset (STO), carrier

Asymptotic Bayesian Decision Feedback Equalizer Using a Set of Hyperplanes

, 2000
We present a signal space partitioning technique for realizing the optimal Bayesian decision feedback equalizer (DFE). It is known that, when the signal to noise ratio (SNR) tends to infinity, the decision boundary of the Bayesian DFE is asymptotically ...

Generalized Multicarrier CDMA: Unification and Linear Equalization

EURASIP Journal on Advances in Signal Processing, 2005
Relying on block-symbol spreading and judicious design of user codes, this paper builds on the generalized multicarrier (GMC) quasisynchronous CDMA system that is capable of multiuser interference (MUI) elimination and intersymbol interference (ISI ...
