Performance of Monobit Digital Receivers with Inter-Symbol Interference
IEEE Wireless Communications Letters, 2014Implementation complexity and power consumption are the two most crucial problems in impulse radio (IR) communications, which is seen as a promising contender for broadband wireless systems. To address such issues, monobit sampling with Nyquist rate was introduced, and the corresponding receiver without inter-symbol interference (ISI) was obtained.

A multirate transmission scheme to mitigate intersymbol interference (ISI) is proposed in this paper. The proposed method first decomposes the channel into two half-rate subchannels by employing successive interference cancellation (SIC). Then the channel is further decomposed into 2M parallel channels by applying the method recursively. We demonstrate

Physical layer authentication using controlled inter symbol interference
2012 IEEE International Symposium on Dynamic Spectrum Access Networks, 2012Spectrum security and enforcement is one of the major challenges that need to be addressed before cognitive radios (CR) can be widely deployed for opportunistic spectrum sharing. One of the mechanisms needed to carry out spectrum enforcement is the authentication or identification of transmitters.

PHY-layer authentication by introducing controlled inter symbol interference
2013 IEEE Conference on Communications and Network Security (CNS), 2013Spectrum security and enforcement is one of the major challenges that need to be addressed before spectrum-agile and opportunistic spectrum access technologies can be deployed. Rogue transmitters are a major threat to opportunistic spectrum access.

Extrinsic Neural Network Equalizer for Channels with High Inter-Symbol-Interference
ICC 2021 - IEEE International Conference on Communications, 2021In this paper, we propose a novel extrinsic neural network equalizer (ExNE) for joint iterative equalization and decoding. The proposed ExNE takes the received signal sequence and a priori probabilities from the channel decoder as inputs to directly generate output extrinsic probabilities.

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 ...

Inter-symbol interference (ISI) in on-die transmission lines
2009 IEEE International Conference on Microwaves, Communications, Antennas and Electronics Systems, 2009The waveforms of a signal transmitted through single-ended on-die transmission lines, implemented by standard metal layers of a CMOS 45 nm technology node, have been experimentally studied. The influence of the active loss level of the lines, as well as of the impedance mismatch between the transmission line and its driver upon the signal distortion ...

Modulated laser radar decoding by inter symbol interference
SPIE Proceedings, 2011Pseudo Random Noise (PN) coded laser radar can improve the target detection ability without the demand on high power laser. However, the reflected echoes are generally so weak that they are buried in the thermal noise of the receiver, which raises the problem of choosing an optimal threshold for correctly decoding them since the power of echoes ...

Estimation of inter-symbol interference using clock pattern
2015 16th International Conference on Electronic Packaging Technology (ICEPT), 2015Due to advancement in technology and higher demand of frequency, the effect of jitter components, especially inter-symbol interference (ISI), plays significant impact on performance of high speed serial links. The analysis of jitter components is useful for testing of high speed circuits.
