Study on canceling intersymbol interference of inverse-GPS

6th International Conference on Signal Processing, 2002., 2003
In inverse-GPS (Global Positioning System), intersymbol interference greatly influences the positioning error. The paper deals with a new interference canceller by means of which the error is reduced. The interference canceller which we propose is composed of a DLL (delay locked loop) and adaptive filter.

GRAND for Gaussian Intersymbol Interference Channels

CoRR
Channel decoding is a challenging task in communication channels exhibiting memory effects. In this work, we apply the recently proposed decoding paradigm of guessing random additive noise decoding (GRAND) to channels with memory, focusing on linear Gaussian intersymbol interference (ISI) channels.

Performance of Multibeam Satellite Systems with Tomlinson-Harashima Precoding

, 2009
A multibeam satellite system can be modelled as a multiple-input multiple-output (MIMO) system with an interbeam interference matrix that is derived from the positions of the users in the different beams.

Intersymbol interference in DQPSK fibre-optic systems [PDF]

, 2009
The limited bandwidth of high-speed transmitter and receiver hardware gives rise to intersymbol interference (ISI) in digital communication systems. The influence of such ISI is investigated in a low-complexity fiber-optical setting, using differential ...

Multi-User Detection for Group Orthogonal Multi-Carrier Code Division Multiple Access System in Frequency Selective Rayleigh Fading Channel

Journal of Engineering and Sustainable Development, 2008
Code Division Multiple Access (CDMA) suffers from multi-user interference (MUI), and intersymbol interference (ISI) under frequency selective multi-path fading channels. Orthogonal Frequency Division Multiple access (OFDM) is MUI free but achieves lower

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
