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 ...

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 ...

Detection/decoding over channels with synchronization errors and inter-symbol interference
2012 IEEE International Conference on Communications (ICC), 2012We consider coding schemes over an independent and identically distributed (i.i.d.) insertion/deletion channel with inter-symbol interference (ISI). The idea is based on a serial concatenation of a low-density parity check (LDPC) code with a marker code.

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.

Inter-symbol interference compensation for bit patterned media recording storage
2015 International Conference on Information Networking (ICOIN), 2015Bit patterned media recording is one of the candidates for the next generation magnetic data storage. When the storage density is increased, the space between the islands narrows. Therefore, it has inter-symbol interference (ISI) in all directions, unlike in the serially in-and-out storage systems.

A Blind CM Receiver for STBC over Channels with Inter-Symbol Interference
2007 IEEE International Symposium on Signal Processing and Information Technology, 2007Alamouti's Space-Time Block Coding (STBC) scheme has received considerable attention due to its ability to maximize the diversity gain of a Multi-Input-Multi-Output (MIMO) transmission link. For frequency selective fading, only a few receivers can be found in the literature. These are mainly trained and block based, such as Time Reversal STBC (TRSTBC),

Coding and Detection for Channels With Written-In Errors and Inter-Symbol Interference
IEEE Transactions on Magnetics, 2014Written-in errors (WIEs), which include written-in substitutions, insertions, and deletions, as well as 2-D inter-symbol interference (2-D-ISI), form one of the major challenges for the new emerging bit-patterned media recording technology. Coding and detection scheme with performance/complexity tradeoffs is expected to address such a challenge.

Joint estimation of data and timing in the presence of inter-symbol interference
IEEE Transactions on Magnetics, 2003A channel with inter-symbol interference and random perturbations to timing is approximated using a finite-state Markov model. The inter-symbol interference is approximated by a finite-impulse response and the timing perturbations are approximated by a first-order random walk.

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

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 ...
