Efficient Transmission of an Encrypted Image through a MIMO-OFDM System with Different Schemes

Abstract

The rapid advancements in wireless communication 
systems have spurred the need for efficient and secure 
methods for transmitting sensitive data, including 
encrypted images. This study explores the 
integration of Multiple-Input Multiple-Output 
(MIMO) and Orthogonal Frequency Division 
Multiplexing (OFDM) systems to achieve high
throughput, robust, and secure transmission of 
encrypted images. The MIMO-OFDM framework is 
recognized for its ability to mitigate multipath 
fading, improve spectral efficiency, and support high 
data rates. However, ensuring data confidentiality 
while maintaining efficiency in such systems presents 
unique challenges. 
This work investigates various encryption schemes 
tailored to image data, including traditional 
cryptographic methods, chaotic systems, and hybrid 
encryption 
techniques, 
emphasizing 
their 
compatibility with MIMO-OFDM systems. The 
performance of the proposed approach is evaluated 
under different channel conditions, considering 
factors like encryption overhead, transmission 
efficiency, and security resilience. Comparative 
analysis with existing systems demonstrates the 
effectiveness of optimized encryption techniques in 
maintaining image quality and reducing latency 
without compromising security. 
The results highlight the potential of MIMO-OFDM 
systems for secure and efficient encrypted image 
transmission, paving the way for their application in 
areas such as medical imaging, secure surveillance,and real-time multimedia sharing. This study 
provides a comprehensive framework for balancing 
performance, security, and efficiency, offering a 
robust solution for the growing demands of next
generation wireless communication networks.
