Adaptive Canonical Correlation Analysis With Application to Time Synchronization for Signal Alignment

ICASSP 2025accepted

Signal Alignment has been recently introduced as a simple and effective means of communicating under powerful and unpredictable (e.g., intermittent) interference. Signal alignment uses repetition coding at the transmitter and canonical correlation analysis (CCA) at the (multi-antenna) receiver to sy…

Binary Signal Alignment: Optimal Solution is Polynomial-Time and Linear-Time Solution is Quasi-Optimal

ICASSP 2024accepted

In this paper we revisit a recently proposed underlay communication scheme which relies on repetition of the secondary signal at the transmitter and canonical correlation analysis CCA at the (multi-antenna) receiver. In this setting, CCA can provably extract the underlay signal in the presence of po…
