Kablosuz Yüksek Çözünürlüklü Video İletimi için SDR Tabanlı Adaptif Platform Tasarımı

Öz

Yüksek çözünürlüklü kablosuz görüntü iletimi, savunma, sağlık ve eğitim gibi alanlarda kullanılan modern haberleşme sistemleri için büyük önem taşımaktadır. Gerçek zamanlı ve yüksek hızlı veri iletimine yönelik artan ihtiyaç, geleneksel donanım tabanlı sistemlerin yetersizliklerini ortaya koymaktadır. OFDM, yüksek veri hızına sahip olması ve kanal bozulmalarına karşı dayanıklılık sunmasına rağmen; modülasyon türü, FFT boyutu ve çevrimsel ön ek gibi parametrelerin sabit olması nedeniyle esneklikten yoksundur. Bu çalışma, bu sınırlamaları aşmak amacıyla Yazılım Tanımlı Radyo (SDR) teknolojisi ile entegre edilmiş konfigüre edilebilir bir OFDM tabanlı kablosuz iletim platformunun tasarımını sunmaktadır. Önerilen sistem, temel iletişim parametrelerinin yazılım yoluyla gerçek zamanlı olarak değiştirilmesine olanak tanımakta ve böylece donanım değişikliğine gerek duymamaktadur. Tasarlanan bu platform, yüksek çözünürlüklü kablosuz iletişim uygulamaları için esnek, uyarlanabilir ve maliyet etkin bir çözüm sunmaktadır.

SDR-Based Adaptive Platform Design for Wireless High-Resolution Video Transmission

Öz

High-resolution wireless video transmission is essential in modern communication systems, particularly in sectors like defense, healthcare, and education. The growing need for real-time, high-speed data transfer in dynamic wireless environments reveals the limitations of traditional hardware-based systems. OFDM offers high data rates and resilience against channel impairments, yet standardized implementations lack flexibility due to fixed parameters. This study presents the design of a configurable OFDM-based wireless transmission platform integrated with Software Defined Radio (SDR) technology. The proposed system enables real-time, software-based adaptation of key parameters such as modulation, coding, and encryption, eliminating the need for hardware modifications. This flexibility allows the system to respond effectively to varying channel conditions while maintaining high performance. The designed platform provides a scalable, adaptable, and cost-efficient solution for high-resolution wireless communication applications.
