Canceling Interferences for High Data Rate Time Reversal MIMO UWB System: A Precoding Approach

EURASIP Journal on Wireless Communications and Networking, 2011
An ultra-high data rate time reversal (TR) multiple-input multiple-output (MIMO) ultra-wideband (UWB) communication system with space-time precoding is proposed.

OFDM Signal Recovery in Deep Faded Erasure Channel

IEEE Access, 2019
In high-speed digital wireless communication applications, the intersymbol interference channel may have spectral nulls or erasures, which may degrade the orthogonal frequency division multiplexing (OFDM) bit error rate (BER) performance.

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.

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
