Filter Bank Multi-carrier Waveform Design for Low Probability of Intercepting Joint Radar and Communication System

open access: yesLeida xuebao, 2023
Cyclic prefixes in joint radar and communication systems based on Orthogonal Frequency Division Multiplexing (OFDM) and low probability of interception lead to weak radar echo masking on the battlefield.

Continuity of Quantum Channel Capacities [PDF]

open access: yesCommunications in Mathematical Physics, 2009
We prove that a broad array of capacities of a quantum channel are continuous. That is, two channels that are close with respect to the diamond norm have correspondingly similar communication capabilities. We first show that the classical capacity, quantum capacity, and private classical capacity are continuous, with the variation on arguments epsilon ...

The capacity region of broadcast channels with intersymbol interference and colored Gaussian noise [PDF]

open access: yes, 2001
We derive the capacity region for a broadcast channel with intersymbol interference (ISI) and colored Gaussian noise under an input power constraint. The region is obtained by first defining a similar channel model, the circular broadcast channel, which ...

Inner and Outer Bounds for the Gaussian Cognitive Interference Channel and New Capacity Results [PDF]

open access: yes, 2010
The capacity of the Gaussian cognitive interference channel, a variation of the classical two-user interference channel where one of the transmitters (referred to as cognitive) has knowledge of both messages, is known in several parameter regimes but ...

Insights into pegRNA design from editing of the cardiomyopathy‐associated phospholamban R14del mutation

open access: yesFEBS Letters, EarlyView.
This study reveals how prime editing guide RNA (pegRNA) secondary structure and reverse transcriptase template length affect prime editing efficiency in correcting the phospholamban R14del cardiomyopathy‐associated mutation. Insights support the design of structurally optimized enhanced pegRNAs for precise gene therapy.

Space Alignment Based on Regularized Inversion Precoding in Cognitive Transmission [PDF]

open access: yesRadioengineering, 2015
For a two-tier Multiple-Input Multiple-Output (MIMO) cognitive network with common receiver, the precoding matrix has a compact relationship with the capacity performance in the unlicensed secondary system.

Optimal Power Allocation for Hybrid Cognitive Cooperative Radio Networks With Imperfect Spectrum Sensing

open access: yesIEEE Access, 2018
In this paper, two optimal power allocation strategies for hybrid interweave-underlay cognitive cooperative radio networks (CCRNs) are proposed to maximize channel capacity and minimize outage probability.

On the Secrecy Capacity of Fading Channels [PDF]

open access: yes2007 IEEE International Symposium on Information Theory, 2007
We consider the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper. Our eavesdropper can be viewed as the wireless counterpart of Wyner's wiretapper. The secrecy capacity of such a system is characterized under the assumption of asymptotically long coherence intervals. We first consider the full Channel

Classical capacity of bosonic broadcast communication and a new minimum output entropy conjecture

open access: yes, 2007
Previous work on the classical information capacities of bosonic channels has established the capacity of the single-user pure-loss channel, bounded the capacity of the single-user thermal-noise channel, and bounded the capacity region of the multiple ...
