Inter-symbol interference analysis of synaptic channel in molecular communications
2014 IEEE International Conference on Communications (ICC), 2014Neuro-spike communication is an important branch of molecular communications and has attracted much attention recently. Seminal works on the analyses of signal processing and channel models for the synaptic communication have recently been carried out. However, these works do not consider interference.

Data-Aided Channel Estimation for Poisson Channels With Inter-Symbol Interference
ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020It has been shown that long pilots should be employed in a Poisson channel with inter-symbol interference to obtain accurate channel estimate, which may reduce the transmission efficiency. In this paper, an iterative data-aided channel estimation and signal detection algorithm is proposed with significant shortened overhead but can approach the bit ...

On the Inter-Symbol-Interference in several Ultra Wideband systems
2005 2nd International Symposium on Wireless Communication Systems, 2005The performance of several ultra-wideband (UWB) transmission schemes is analysed when the channel is frequency selective so that inter-symbol-interference (ISI) arises at the receiver. The UWB schemes considered employ time hopping (TH) and/or direct sequence (DS) as spreading method and a correlation receiver.

Inter-Symbol Interference Mitigation in High-Data-Rate UWB Systems
2007 IEEE International Conference on Communications, 2007The design of ultra-wideband (UWB) impulse radio receivers has to cope with complex signal propagation environments with dense multipath fading, which complicate channel estimation and multipath energy capture. As the date transmission rate increases, additional interference between adjacent symbols arises which may further degrade the detector ...

Inter-Symbol-Interference Reduction in Continuous Variable QKD Using Equalization
2018 IEEE Globecom Workshops (GC Wkshps), 2018Inter-symbol-interference (ISI) noise in Continuous Variable Quantum Key Distribution (CVQKD) is caused by the overlap between the consecutive detected signals. In practice, this problem limits the repetition rate of the quantum signals for a given bandwidth detector and hence reduces the rate of secure key generation.

A novel iterative scheme for parallel inter-symbol interference channels
Journal of Electronics (China), 2007In this paper, we propose a novel iterative scheme for exploiting transmit diversity using parallel independent Inter-Symbol Interference (ISI) channels. In this adaptive iterative scheme, we use EXtrinsic Information Transfer (EXIT) chart tool to choose appropriate iterative method from Iterative Combining (IC), used as parallel concatenation turbo ...

Capacity Bounds for Mimo Poisson Channels with Inter-symbol interference
2006We study multiple-access Poisson channels with multiple receivers. Each transmitter sends a sequence of modulated symbols, which may also be affected by inter-symbol interference. We derive some new formulas for the channel capacity, for the cases of both independent and coordinated transmission. We also provide some numerical results on the additional

Inter-symbol Interference in High Data Rate Transmit Reference UWB Transceivers
2007 IEEE International Conference on Ultra-Wideband, 2007Ultra Wideband (UWB) Systems take advantage of collecting energy from a large number of multipaths. In high data rate systems, the leakage of these paths among symbols may cause severe inter-symbol interference (ISI) and degrade performance. A few techniques were presented in the past to improve non-coherent receiver performance in the presence of ISI.

Inter-symbol-Interference Reduction in Indoor Infrared Systems by Effective Sampling
2009 International Conference on Future Computer and Communication, 2009— A new and simple receiver structure for reducing the multipath inter-symbole interference (ISI) effect is proposed for infrared diffuse links. In this new method, bit-error rate (BER) performance of the system will be improved significantly without any essential change in the receiver structure.

Inter-symbol interference free pulses for transmission over Intensity-Modulated Channels
2014 10th International Conference on Communications (COMM), 2014Motivated by the recent and rapid development in high speed data transmission systems for optical communications, this paper analyses a class of inter-symbol interference (ISI) free pulses for transmission over intensity-modulated channels. The future trend will probably migrate toward low-complexity and cost effective systems.
