Joint Optimization of Codeword Bit Distribution and Detection Threshold for Asymmetric STT-MRAM Channel [PDF]

Sensors
Asymmetric error characteristics in spin-transfer torque magnetic random-access memory (STT-MRAM), particularly the imbalance between logical ‘0’ and ‘1’ error probabilities, can significantly degrade system reliability under conventional modulation and ...

Energy Detection of Unknown Signals over Cascaded Fading Channels [PDF]

IEEE Antennas and Wireless Propagation Letters, 2015
Energy detection is a favorable mechanism in several applications relating to the identification of deterministic unknown signals such as in radar systems and cognitive radio communications. The present work quantifies the detrimental effects of cascaded

Channelization cascade in landscape evolution [PDF]

Proceedings of the National Academy of Sciences, 2020
The hierarchy of channel networks in landscapes displays features that are characteristic of nonequilibrium complex systems. Here we show that a sequence of increasingly complex ridge and valley networks is produced by a system of partial differential equations coupling landscape evolution dynamics with a specific catchment area equation. By means of a

Secure Cascade Channel Synthesis [PDF]

IEEE Transactions on Information Theory, 2013
We consider the problem of generating correlated random variables in a distributed fashion, where communication is constrained to a cascade network. The first node in the cascade observes an i.i.d. sequence $X^n$ locally before initiating communication along the cascade. All nodes share bits of common randomness that are independent of $X^n$.

Hypothesis testing over cascade channels [PDF]

2017 IEEE Information Theory Workshop (ITW), 2017
Binary hypothesis testing over single and parallel cascade channels is considered where sensors communicate with dedicated relays, and these relays with a single final receiver. All relays as well as the final receiver decide on the binary hypothesis governing the joint probability distribution of the observations at the sensors, relays, and final ...

Cascade: Channel-Aware Structured Cosparse Audio Declipper [PDF]

2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018
This work features a new algorithm, CASCADE, which leverages a structured cosparse prior across channels to address the multichannel audio declipping problem. CASCADE technique outperforms the state-of-the-art method A-SPADE applied on each channel separately in all tested settings, while retaining similar runtime.
