Turbo Detection of Space-time Trellis-Coded Constant Bit Rate Vector-Quantised Videophone System using Reversible Variable-Length Codes, Convolutional Codes and Turbo Codes

open access: yes, 2004
In this treatise we characterise the achievable performance of a proprietary video transmission system, which employs a Constant Bit Rate (CBR) video codec that is concatenated with one of three error correction codecs, namely a Reversible Variable ...

Noisy quantum trees: infinite protection without correction

open access: yesnpj Quantum Information
We study quantum networks with tree structures, in which information propagates from a root to leaves. At each node in the network, the received qubit unitarily interacts with fresh ancilla qubits, after which each qubit is sent through a noisy channel ...

A Concatenated Dual Displacement Code for Continuous-Variable Quantum Error Correction

open access: yes
The continuous-variable (CV) Gaussian no-go theorem fundamentally limits the suppression of Gaussian displacement errors using only Gaussian gates and states. Prior studies have employed Gottesman-Kitaev-Preskill (GKP) states as ancillary qumodes to suppress small Gaussian displacement errors, but when the displacement magnitude becomes large, lattice ...

Serially Concatenation of Forward Error Correction Codes for Real Time Applications

open access: yesJournal of Engineering and Sustainable Development, 2014
his paper presents a scheme of serially concatenated codes. It is formed by Bose Chaudhuri Hocquenghem (BCH) as outer code and Low-density Parity Check (LDPC) inner code in order to real-time applications by getting rid of the delay time stem from a large number of iterations of LDPC decoder.
