On the Performance of Wireless Video Communication Using Iterative Joint Source Channel Decoding and Transmitter Diversity Gain Technique

Wireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 2020
In this research work, we have presented an iterative joint source channel decoding‐ (IJSCD‐) based wireless video communication system. The anticipated transmission system is using the sphere packing (SP) modulation assisted differential space‐time spreading (DSTS) multiple input‐multiple output (MIMO) scheme.

Reliable UAV Video Streaming Over 5.9 GHz and mmWave Bands: Comparative Analysis With Fountain Codes in Urban and Industrial Environments

IET Communications, Volume 20, Issue 1, January/December 2026.
This article presents an adaptive unmanned aerial vehicle video streaming framework in which captured video is encoded at multiple quality levels and protected using Luby transform (LT) coding before transmission over a wireless channel to a base station. At the receiver, LT decoding and latency monitoring are used to assess delivery performance, while

A Fast Enhanced Secure Image Chaotic Cryptosystem Based on Hybrid Chaotic Magic Transform

Modelling and Simulation in Engineering, Volume 2017, Issue 1, 2017., 2017
An enhanced secure image chaotic cryptosystem has been proposed based on hybrid CMT‐Lanczos algorithm. We have achieved fast encryption and decryption along with privacy of images. The pseudorandom generator has been used along with Lanczos algorithm to generate root characteristics and eigenvectors.
