The capability of multilevel input ring-TCM coding scheme for generating high-rate codes with improved symbol Hamming and squared Euclidean distances is demonstrated. The existence of uniform codes and the decoder complexity are also considered.

In this paper, we propose a new scalar linear coding scheme for the index problem called update-based maximum column distance (UMCD) scheme. The central idea in each transmission is to code messages such that one of receivers with minimum size side information instantaneously eliminated from unsatisfied receivers. One main contribution paper prove other satisfied can be identified after transmi...

An enhanced FEC system is proposed and described. The scheme has been simulated with both Single carrier and Multi-carrier (OFDM) Modulation. Purpose This proposal is offered as a basis for FEC in the 802.16.3 PHY layer. Notice This document has been prepared to assist IEEE 802.16. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). T...

Introduction The goal is to develop a numerical index of well being (adaptation) from skeletal data. Knowledge of both economic indicators (such as Gross National Product) and health status assessments suggest that useful indices can be developed from imperfect data. Our collection of skeletal data represent a large array of genetic, geographic, and temporal groups, which permit us to measure l...
