Robust Binary Quantizers for Distributed Detection

Ying Lin, Biao Chen, Bruce Suter
2007 IEEE Transactions on Wireless Communications  
Two different optimization criteria are used in the distributed quantizer design, the first a constrained optimization problem, and the second using an erasure channel model.  ...  We consider robust signal processing techniques for inference-centric distributed sensor networks operating in the presence of possible sensor failures and/or communication failures.  ...  In each plot, (b) is a zoom-in of (a) for better visualization. • Fig. 6 is the error probability versus erasure probability plot.  ...

2005 IEEE Transactions on Signal Processing  
Simulations show that both techniques can render error performance that is better than Kalman-PDA alone and competitive to sphere decoding.  ...  At the same time, all the interference affecting the local subblock, including both multiple access and intersymbol interference (ISI), is properly modeled as the state vector of a linear system and dynamically  ...  (ARQ), and/or erasure decoding.  ...

Machine Learning for Error Correction with Natural Redundancy [article]

Pulakesh Upadhyaya, Anxiao Jiang
2019 arXiv   pre-print
The second approach, called Representation-Aware, assumes that such knowledge is known and uses it for error correction. Furthermore, both approaches combine the decoding based on NR and ECCs.  ...  It uses deep learning to detect file types accurately, and then mine Natural Redundancy for soft decoding.  ...  In practice, it is worthwhile to study the properties of Natural Redundancy (e.g., whether the redundancy is mainly local or global, which differs for different types of data), and choose appropriate coding  ...

Routing for multimedia traffic in wireless frequency-hop communication networks

M.B. Pursley, H.B. Russell, P.E. Staples
1999 IEEE Journal on Selected Areas in Communications  
In such an application, voice packets cannot tolerate much delay, but they are allowed to contain a small number of frame erasures while data packets must be delivered error-free even if a moderate delay  ...  The method is illustrated for traffic of two types, each type having its own throughput, delay, and error-rate requirements.  ...  A received word that has no more than erasures and errors is decoded correctly if does not exceed .  ...

Julian Chesterfield, Pablo Rodriguez
2005 Proceedings of the 3rd international conference on Mobile systems, applications, and services - MobiSys '05  
To this extent, we present DeltaCast, a system that combines hierarchical hashes and erasure codes to minimise the amount of battery power and the amount of time needed to synchronise each mobile device  ...  In this paper we consider the problem of efficiently updating files in such wireless broadcast channels.  ...  There is a tradeoff in utilising erasure coding in terms of the decoding requirements and consequently additional power is consumed by the device in the process of decoding erasure blocks, however we maintain  ...
