Turbo equalization and an M-BCJR algorithm for strongly narrowband intersymbol interference [Elektronisk resurs] [PDF]
, 2010 An M-BCJR algorithm is proposed and tested over an AWGN channel with moderate to very intense intersymbol interference (ISI). Two M-BCJR applications are evaluated, simple detection over the ISI channel and turbo equalization.

Interference Mitigation in Cooperative SFBC-OFDM
EURASIP Journal on Advances in Signal Processing, 2008 We consider cooperative space-frequency block-coded OFDM (SFBC-OFDM) networks with amplify-and-forward (AF) and decode-and-forward (DF) protocols at the relays. In cooperative SFBC-OFDM networks that employ DF protocol, (i), intersymbol interference (ISI)

Information rates of energy harvesting communications with intersymbol interference
, 2019 We consider energy harvesting communications over an intersymbol interference (ISI) channel corrupted by additive white Gaussian noise. We assume that the energy arrivals at the transmitter, which is equipped with a finite battery, are independent and ...

On the capacity and normalisation of ISI channels [PDF]
, 2003 We investigate the capacity of various intersymbol interference (ISI) channels with additive white Gaussian noise (AWGN). Previous papers showed a minimum Eb/No of -4.6 dB, 3 dB below the capacity of a flat channel, is obtained using water-pouring ...

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.In this paper, optical routers play an indispensable role in the ONoCs. The 4 × 4, 5 × 5, and scalable optical routers based on Mach–Zehnder interferometer (MZI) and microring resonator (MRR) are proposed. These routers are designed for a deadlock‐free Odd–Even turning model.

Three design aspects of multicarrier interleave division multiple access [PDF]
, 2008 This paper presents a novel generalized transceiver architecture, i.e., Multicarrier Interleave-Division-Multiplexing-aided Interleave Division Multiple Access (MC-IDM-IDMA). A parallel interference cancellation (PIC)-aided iterative multiuser detection (

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.This research paper proposes three joint transmit and receive (TX/RX) beamforming schemes for minimizing the bit error rates of next‐generation wireless sensor networks. Based on minimizing the optimization problem of the total mean squared error between the transmitted and received data symbols, the first beamforming scheme is proposed.

Near-capacity three-stage MMSE turbo equalization using irregular convolutional codes
, 2006 Traditional Turbo EQualization (TEQ) schemes suffer from residual bit errors due to the non-recursive nature of the channel imposing Inter-Symbol-Interference (ISI).

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2025, Issue 1, 2025.Wavelength division multiplexing (WDM) technology is widely used in high‐capacity optical communication systems, enabling the simultaneous transmission of multiple signals over optical fiber. However, signal attenuation and dispersion pose significant challenges to long‐distance optical transmission.
