Absfmcf-The paper describes the possible implementation of concatenated coding scheme suitable particularly for high date rate applications. The proposed coding scheme uses a set of n convolutional codes multiplexed into an inner code and a (n, n 1) single-parity-check code servi
Improved Space-Time Coding Scheme over Nakagami Fading Channels
In this paper, the performance of space-time coding scheme is investigated over Nakagami fading channels. In the first part, the performance of super-orthogonal space-time trellis code is presented while the performance of its concatenated version is presented in the second part.
Block Coding Schemes Designed for Biometric Authentication
We address the biometric authentication setup where the outcomes of biometric observations received at the verification stage are compared with the sample data formed at the enrollment stage. The result of comparison is either the acceptance or the rejection of the identity claim
Performance Evaluation of Physical Layer of Mobile WiMAX System by Implementing Hybrid Channel Coding Scheme
The demand of wireless communication is high data rate along with error free communication. An error in communication can be reduced by employing proper channel coding techniques. In this paper, authors have proposed the hybrid channel coding scheme in which convolution codes and
Capacity-achieving and Flicker-free FEC coding scheme for Dimmable Visible Light Communication Based on Polar Codes
Visible light communication (VLC) could provide short-range optical wireless communication together with illumination using LED lighting. However, conventional forward error correction (FEC) codes for reliable communication do not have the features for dimming support and flicker
A Comparative Study of IEEE 802.11p Physical Layer Coding Schemes and FPGA Implementation for Inter Vehicle Communications
This paper provides a comprehensive investigation of the performance and practical implementation issues of two coding schemes, employing Concatenated Reed Solomon Codes with Convolutional Codes and Turbo Codes, over vehicular ad-hoc networks based on the IEEE 802.11p specificati
Analysis of Network Coding Schemes for Differential Chaos Shift Keying Communication System
In this paper we design network coding schemes for Differential Chaos Shift Keying (DCSK) modulation. In this work, non-coherent chaos-based communication system is used due to its simplicity and robustness to multipath propagation effects, while dispensing with any channel state
Digital line segment coding: A new efficient contour coding scheme
A new coding scheme is proposed for two-tone image contours. The basic idea is to detect digital line segments on the contour and code them using fixedor variable-length codewords; the present work deals mainly with fixed-length codewords. It is demonstrated that the conventional
Unveiling Turbo Codes: Some Results on Parallel Concatenated Coding Schemes - Information Theory, IEEE Transactions on
AbstructA parallel concatenated coding scheme consists of two simple constituent systematic encoders linked by an interleaver. The input bits to the first encoder are scrambled by the interleaver before entering the second encoder. The codeword of the parallel concatenated code c
Context-Based Arithmetic Coding Scheme for Parametric Stereo in Enhanced aacPlus
Enhanced aacPlus is an audio codec which is composed of advanced audio coding (AAC), spectral band replication (SBR), and parametric stereo (PS) for efficient audio coding at low bit rates. We propose a new coding scheme for lossless bit rate reduction of PS in enhanced aacPlus.
