Capacity Analysis for Tunnel Diode Amplifier Assisted Ambient Backscatter Communications
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]
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]
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.

The channel capacity of the postal channel
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]
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.
