Toward Robust MIMO and Spread-Spectrum Wireless Image Transmission: Deep Joint Source–Channel Autoencoding with Adaptive Rate Control and Task-Oriented Semantic Attention
Deep joint source–channel coding (Deep JSCC) provides an end-to-end alternative to separated image compression and channel coding, but reconstruction fidelity, channel use, and task utility are distinct design objectives. This study evaluates these objectives in three coordinated experimental tracks. The reconstruction...
