Shannon lower bound

Webb14 apr. 2024 · The local structure present in Wigner and Husimi phase-space distributions and their marginals are studied and quantified via information-theoretic quantities. Shannon, R\'enyi, and cumulative residual entropies of the Wigner and Husimi distributions are examined in the ground and excited states of a harmonic oscillator. The entropies of … WebbThen, the Shannon lower bound (SLB) is defined by (8) where is the differential entropy of the probability density p, and s is related to D by (9) The next lemma shows that the SLB …

Webb6 feb. 2012 · Abstract. In this note we formally show a "folklore" (but, to the best of our knowledge, not documented) fact that in order to beat the famous Shannon lower bound on key length for one-time-secure encryption, one must *simultaneously* restrict the attacker to be efficient, and also allow the attacker to break the system with some non … WebbOne, we challenge in this paper, is the lower reception bound (Eb,/No)min. This bound is not ln(2), as Shannon’s theory states, but zero. The architecture of the receiver and environ …

WebbShannon gave a lower bound in 1959 on the binary rate of spherical codes of given minimum Euclidean distance $\rho$. Using nonconstructive codes over a finite alphabet, we give a lower bound that is weaker but very close for small values of $\rho$. Webb30 aug. 2016 · Thus, the Shannon lower bound provides an asymptotically tight bound on the rate-distortion function if, and only if, the integer part of the source has finite entropy. …

WebbThe Shannon Lower Bound is Asymptotically Tight Tobias Koch, Member, IEEE Abstract—The Shannon lower bound is one of the few lower bounds on the rate-distortion function that holds for a large class of sources. In this paper, which considers exclusively norm-based difference distortion measures, it is demonstrated that Webb1 mars 2024 · This leads to an improved lower bound on the Shannon capacity of C 7: Θ (C 7) ≥ 367 1 / 5 > 3.2578. The independent set is found by computer, using the fact that the set { t ⋅ ( 1 , 7 , 7 2 , 7 3 , 7 4 ) t ∈ Z 382 } ⊆ Z 382 5 is independent in the fifth strong product power of the circular graph C 108 , 382 .
