Noncoherent ISAC over Block-Fading Channels: Asymptotic Performance Analysis
Hao Yang, Kai Wan, Giuseppe Caire
This paper investigates the fundamental limits and optimal signal distribution design for Integrated Sensing and Communication (ISAC) systems operating under strictly noncoherent c…
Codebook Design and Baseband Precoding for Pragmatic Array-Fed RIS Hybrid Multiuser MIMO
Krishan Kumar Tiwari, Giuseppe Caire
In our previous work [2], we introduced a hardware- and power-efficient architecture for hybrid digital-analog (HDA) multiuser MIMO (MU-MIMO) based on stacking identical basic modu…
A Unified Multicarrier Waveform Framework for Next-generation Wireless Networks: Principles, Performance, and Challenges
Xingyao Zhang, Haoran Yin, Yanqun Tang +7
Next-generation wireless networks require enhanced flexibility, efficiency, and reliability in physical layer waveform design to address the challenges posed by heterogeneous chann…
Sparse Regression LDPC Codes for the Block-Fading Non-Coherent SIMO Channel
Alexander Fengler, Burak Ãakmak, Giuseppe Caire
Sparse regression codes (SPARCs) are a class of codes that encode information through the superposition of columns of a randomised coding matrix. The combination with an outer non-…
