Quantum Capacity Approaching Codes for the Detected-Jump Channel
, 2010 The quantum channel capacity gives the ultimate limit for the rate at which quantum data can be reliably transmitted through a noisy quantum channel. Degradable quantum channels are among the few channels whose quantum capacities are known.

How Well Can We Infer Selection Benefits and Mutation Rates from Allele Frequencies?
Entropy, 2023 Experimentalists observe allele frequency distributions and try to infer mutation rates and selection coefficients. How easy is this? We calculate limits to their ability in the context of the Wright-Fisher model by first finding the maximal amount of ...

Capacity Approximations for a Deterministic MIMO Channel
Advances in Electrical and Computer Engineering, 2011 In this paper, we derive closed form approximations for the capacity of a point-to-point, deterministic Gaussian MIMO communication channel. We focus on the behavior of the inverse eigenvalues of the Gram matrix associated with the gain matrix of the ...

Capacity Analysis and Data Detection of OvTDM-MIMO System
IEEE Access, 2023 It is well known that the channel capacity of traditional MIMO systems is positively correlated with the number of antennas, so MIMO systems usually use more antennas to meet higher system capacity requirements, which is increasingly conflicting with the

Trade-off coding for universal qudit cloners motivated by the Unruh effect [PDF]
, 2011 A "triple trade-off" capacity region of a noisy quantum channel provides a more complete description of its capabilities than does a single capacity formula.

A simple Encoding Scheme to Achieve the Capacity of Half-Duplex Relay Channel
Advances in Electrical and Electronic Engineering, 2022 In this paper, the Half-Duplex Relay Channel (HDRC) is thoroughly investigated. Even though this channel model is widely studied, the capacity is not yet fully understood and particularly has not been tightly expressed.
