The PSK Channel Capacity Estimation under Dynamic Plasma Sheath Channel

open access: yesInternational Journal of Antennas and Propagation, 2020
During the reentry process, the plasma sheath covering the surface of the hypersonic aircraft will cause the amplitude attenuation and phase jitter of the communication electromagnetic waves.

Capacity Analysis for Tunnel Diode Amplifier Assisted Ambient Backscatter Communications

open access: yesIEEE Access, 2022
Ambient backscatter communication (AmBC) addresses connectivity, cost, and congestion bottlenecks for the Internet of Things (IoT) deployment. AmBC, by avoiding a dedicated power infrastructure and carrier emitter, allows tags to communicate by simply ...

Channel coding: The road to channel capacity [PDF]

open access: yesProceedings of the IEEE, 2007
Starting from Shannon's celebrated 1948 channel coding theorem, we trace the evolution of channel coding from Hamming codes to capacity-approaching codes. We focus on the contributions that have led to the most significant improvements in performance vs.

Multipath channels of unbounded capacity [PDF]

open access: yes2008 IEEE 25th Convention of Electrical and Electronics Engineers in Israel, 2008
The capacity of discrete-time, non-coherent, multipath fading channels is considered. It is shown that if the delay spread is large in the sense that the variances of the path gains do not decay faster than geometrically, then capacity is bounded in the signal-to-noise ratio.

Remarks on entanglement assisted classical capacity [PDF]

open access: yes, 2003
The property of the optimal signal ensembles of entanglement assisted channel capacity is studied. A relationship between entanglement assisted channel capacity and one-shot capacity of unassisted channel is obtained.

The channel capacity of the postal channel

open access: yesInformation and Control, 1970
A mathematical model is proposed for a postal service which occasionally loses letters. A positive coding theorem and a converse is proved for this channel. The coding theorem is proved by utilizing a deterministic code (Reed-Solomon code) and bounded discrepancy decoding.

On the Capacity of Channels With Deletions and States [PDF]

open access: yesIEEE Transactions on Information Theory, 2021
We consider the class of channels formed from the concatenation of a deletion channel and a finite-state channel. For this class of channels, we show that the operational capacity is equal to the stationary capacity, which can be approached by a sequence of Markov processes with increasing Markovian orders.
