Optimal Downlink Training Sequence for Massive MIMO Secret-Key Generation
François Rottenberg
In this paper, the secret-key capacity is maximized by optimizing the downlink training sequence in a time division duplexing (TDD) massive multiple-input-multiple-output (MIMO) sc…
Physical Layer Security in a SISO Communication using Frequency-Domain Time-Reversal OFDM Precoding and Artificial Noise Injection
Sidney Jonathan Golstein, François Rottenberg, François Horlin +2
A frequency domain (FD) time-reversal (TR) precoder is proposed to perform physical layer security (PLS) in single-input single-output (SISO) systems using orthogonal frequency-div…
Channel Extrapolation in FDD Massive MIMO: Theoretical Analysis and Numerical Validation
François Rottenberg, Rui Wang, Jianzhong Zhang +1
Downlink channel estimation in massive MIMO systems is well known to generate a large overhead in frequency division duplex (FDD) mode as the amount of training generally scales wi…
Single-Tap Precoders and Decoders for Multi-User MIMO FBMC-OQAM under Strong Channel Frequency Selectivity
François Rottenberg, Xavier Mestre, François Horlin +1
The design of linear precoders or decoders for multiuser (MU) multiple-input multiple-output (MIMO) filterbank multicarrier (FBMC) modulations in the case of strong channel frequen…
