XLIV Simpósio Brasileiro de Telecomunicações e Processamento de Sinais

Audio bandwidth extension aims to reconstruct missing high-frequency content from bandlimited signals. This paper proposes FiPA-SR, a GAN-based perceptual architecture capable of handling different input bandwidths within a single model. Building upon the previous \(\textrm{AEROMamba}_\textrm{P}\) framework, the proposed model incorporates FiLM layers to...

Sixth-generation (6G) networks integrate sensing and communication (ISAC) to support both high data rates and environmental awareness. In Cell-Free (CF) Massive MIMO systems, distributed access points (APs) enhance spatial diversity, but efficient distributed sensing under realistic propagation conditions remains challenging. This paper proposes the...

Continuous-variable quantum key distribution (CV-QKD) has emerged as a leading protocol for unconditionally secure cryptographic key exchange, leveraging quantum properties of optical signals while remaining compatible with existing telecom infrastructure. In these systems, the receiver's detection capability directly impacts the rate at which...
