With the assistance of singular value decomposition (SVD), a multi-beam directional modulation (DM) scheme based on symmetrical multi-carrier frequency diverse array (FDA) is proposed. The proposed DM scheme is capable of achieving range-angle dependent physical layer secure (PLS) transmissions in free space with much lower complexity than the conventional zero-forcing (ZF) method. Theoretical and simulated results about secrecy rate and complexity verify the improved computational efficiency and considerable memory savings despite a very small penalty of secrecy rate.

  1. WFRFT-aided Power-efficient Multi-beam Directional Modulation Schemes Based on Frequency Diverse Array

    eess.SP 2019-08 conditional novelty 5.0 of 10

    A WFRFT-based multi-beam directional modulation scheme replaces artificial noise with a keyed transform, saving about 1 dB of transmit power while keeping signals secure from eavesdroppers near or at the users' locations.
