Abstract
We present matrix network coding methods that are
naturally amenable to a distributed implementation method, i.e.,
do not require the knowledge of network topology, and that are
suitable for network error correction. First, the Singleton bound
can be K-fold increased by employing a K K matrix coefficient.
Moreover, we prove that matrix network coding outperforms
linear network coding, since it corrects more errors than linear
network coding, while the amount of header overhead per packet
can be kept the same by reducin ....etc

RECENT TRENDS IN IP/NGEO SATELLITE COMMUNICATION SYSTEMS: TRANSPORT, ROUTING, AND MOBILITY MANAGEMENT CONCERNS
ABSTRACT
Non-geostationary (NGEO) satellite communication systems are seen as an attractive solution to realize the vision of anywhere, anytime pervasive access to the Internet. Their design and development have thus gained tremendous interest in the last few years. Commencing with a brief overview of general NGEO satellite configurations, this article next addresses the key technical difficulties in the development o ....etc

ERROR CONTROL CODING



W hen a digital signal is transmitted between two systems(such as computers),the signal gets distorted because of addition of noise to the transmitted signal. The noise can introduce an error in the binary train of bit travelling from one system to the other .this means that a 0 may change to 1 or a 1 may change to 0.These error can become a serious problem to the accuracy and performance of the digital system. Therefore it is essential to detect and correct the er ....etc

Latest trend in electronic and communication has been towards mainly these fields: (1) communication through optical fiber, and (2) microwave (wireless) communication through VSAT networks (3). Free Space Optical communication (4). Adaptive signal processing (5). Ultra Wideband Networks (5) . Multitouch Sensing (6) . Redtaction (7) . Human Area Networks
(i) Optical fiber provides a wider bandwidth and so greater data rate flow through over conventional copper cables. The worldwide internet mainly depends on the optical fiber page link SE ....etc

Introduction

The packet transport service provided by representative packet-switched networks, including IP networks, is not reliable and the quality-of-service cannot be guaranteed. Packets may be lost due to buffer overflow in switching nodes, be discarded due to excessive bit errors and failure to pass the cyclic redundancy check at the page link layer, or be discarded by network control mechanisms as a response to congestion somewhere in the network. Forward Error Correction coding has often been p ....etc

ERROR CONTROL CODING



Basic Concepts

Received: 011. What was transmitted?
scenario A: 111 with one error in 1st location
scenario B: 000 with two errors in 2nd & 3rd locations.

Hamming Distance

Def.: The Hamming distance between two codewords ci and cj, denoted by d(ci,cj), is the number of components at which they differ.

Maximum Likelihood Decoding reduces to Minimum Distance Decoding, if the priory probabilities are equal (P(0)=P(1))
