Can ion-channel biophysics unify physics with biology? can we explain activation without metaphors to rigid everyday devices such as gates? Let us treat the channel an enzyme two allosteric conformations, replacing words “closed” and “open” biophysical concepts “tense” “relaxed.” An electromechanism proposes that elimination of polarization induced within by strong electric field excitable phas...

This paper presents the first proof of polarization for deletion channel with a constant rate and regular hidden-Markov input distribution. A key part this work involves representing using trellis describing plus minus polar-decoding operations on that trellis. In particular, can be seen as combining adjacent stages to yield new half many stages. Using viewpoint, we prove weak theorem standard ...

In this paper, channel capacity of multiple-input multiple-output wireless local area network (MIMO-WLAN) systems with single co-channel interference (CCI) is calculated. A ray-tracing approach is used to calculate the channel frequency response, which is further used to calculate the corresponding channel capacity. The ability to combat CCI for the MIMO-WLAN simple uniform linear array (ULA) a...

Polar lattices, which are constructed from polar codes, are provably good for the additive white Gaussian noise (AWGN) channel. In this work, we propose a new polar lattice construction that achieves the secrecy capacity under the strong secrecy criterion over the mod-Λ Gaussian wiretap channel. This construction leads to an AWGN-good lattice and a secrecy-good lattice simultaneously. The desig...

In this contribution, the 3-dimensional (3D) channel characteristics, particularly in the elevation domains, are extracted through measurements in typical urban macro and micro environments in Xi’an China. Stochastic channel model parameters are obtained based on the high-resolution multi-path parameter estimates. In addition, a modified spatial channel model (SCM) for the line-of-sight (LoS) s...
