Embedding WFRFT Signals Into TDCS for Secure Communications
IEEE Access, 2018 This paper presents a novel combinatory strategy to embed weighted-type fractional Fourier transform (WFRFT) precoding signals into transform domain communication system (TDCS). The original data can be divided into two parts.

Anti‐eavesdropping FrFT‐OFDM system exploiting multipath channel characteristics
IET Communications, 2017 This study exploits wireless channel response and fractional Fourier transform (FrFT) to achieve anti‐eavesdropping downlink transmission over a multipath channel. The proposed system works in time‐division duplexing mode, and only the transmitter knows the main channel response through uplink services.
