Parallel interference cancellation based turbo space-time equalization in the SDMA uplink

, 2007
A novel Parallel Interference Cancellation (PIC) based turbo Space Time Equalizer (STE) structure designed for multiple antenna assisted uplink receivers is introduced. The proposed receiver structure allows the employment of non-linear type of detectors

Graph-Based Channel Detection for Multitrack Recording Channels

EURASIP Journal on Advances in Signal Processing, 2009
We propose a low complexity detection technique for multihead multitrack recording systems. By exploiting sparseness of two-dimensional partial response (PR) channels, we develop an algorithm which performs belief propagation (BP) over corresponding ...

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

2D IMAGE TRANSMISSION USING KALMAN-TURBO SYSTEMS

Electrica, 2005
In this paper, in order to compress and enhance 2D images transmitted over wireless channels, a new scheme called Kalman-Turbo (KT) is introduced. In this scheme, the original image is partitioned into 2N quantization levels and each of the N-bit planes ...

Chained Turbo Equalization for OFDM System without Guard Interval [PDF]

, 2011
This paper proposes Orthogonal Frequency Division Multiplexing (OFDM) system without guard interval using Chained Turbo Equalization (CHATUE) with a doped accumulator to improve the bit-error-rate (BER) performance. OFDM systems commonlyuse cyclic prefix

Direct Adaptive Multi-Resampling Turbo Equalizer for Underwater Acoustic Single-Carrier Communication

Journal of Marine Science and Engineering
A wideband Doppler Effect is a significant challenge for underwater acoustic communications (UAC). This paper proposes a new two-stage structure of direct adaptive multi-resampling turbo equalizer (DAM-TEQ) for solving the problem of large timescale ...
