Low-complexity Detection for Noncoherent Massive MIMO Communications
Marc Vilà -Insa, Jaume Riba
This work studies a point-to-point MIMO uplink in which user equipment transmits data to a base station employing a massive array. Signal detection is noncoherent and fading is ass…
Asymptotic Analysis of Synchronous Signal Processing
Marc Vilà -Insa, Jaume Riba
This paper extends various theoretical results from stationary data processing to cyclostationary (CS) processes under a unified framework. We first derive their asymptotic eigenba…
Low-Complexity Detection of Permutational Index Modulation for Noncoherent Communications
Marc Vilà -Insa, Aniol MartÃ, Meritxell Lamarca +1
This work presents a massive SIMO scheme for wireless communications with one-shot noncoherent detection. It is based on permutational index modulation over OFDM. Its core principl…
Coherent and Noncoherent Detection in Dense Arrays: Can We Ignore Mutual Coupling?
Aniol MartÃ, Luca Sanguinetti, Jaume Riba +1
This paper investigates the impact of mutual coupling on MIMO systems with densely deployed antennas. Leveraging multiport communication theory, we analyze both coherent and noncoh…
Harnessing Wavefront Curvature and Spatial Correlation in Noncoherent MIMO Communications
Aniol MartÃ, Luca Sanguinetti, Meritxell Lamarca +1
Noncoherent communication systems have regained interest due to the growing demand for high-mobility and low-latency applications. Most existing studies using large antenna arrays…
Conditional Dependence via U-Statistics Pruning
Ferran de Cabrera, Marc Vilà -Insa, Jaume Riba
The problem of measuring conditional dependence between two random phenomena arises when a third one (a confounder) has a potential influence on the amount of information between t…
