Hybrid NRZ/RZ line coding scheme based hybrid FSO/FO dual channel communication systems

A Suitable Coding Scheme for Broadband Power-line Communication

This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...

Object-Based Hybrid Image Coding Scheme

An efficient secure channel coding scheme based on polar codes

In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...

A Hybrid Cooperative Coding Scheme for the Relay-Eavesdropper Channel

This paper considers the four-node relay-eavesdropper channel, where a relay node helps the source to send secret messages to the destination in the presence of a passive eavesdropper. For the discrete memoryless case, we propose a hybrid cooperative coding scheme, which is based on the combination of the partial decode-forward scheme, the noise-forward scheme and the random binning scheme. The...

Developing a Hybrid Model Based Coding Scheme for Still Images

Model Based Coding is an idea from the early ages of video telephony. This idea was conceptually as follows: To achieve very low bitrate coding a model of a speaking person was encoded only once and for the remaining telephone call single motion parameters were update only. As network capacities increased the use case of video telephony for video transmission under tough bandwidth constraints c...
