Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …

The computational complexity required in the channel estimation plays an important role in
underwater acoustic communications (UAC) with orthogonal frequency duplex access …

With the wide application of Channel State Information (CSI) in the field of sensing, the
accuracy of positioning accuracy of indoor fingerprint positioning is increasingly necessary …

In this paper, we study the physical layer security problem in the dual‐hop orthogonal
frequency division multiplexing–based wireless communication system. First, we consider a …

Due to the inherent vulnerability of wireless transmission to eavesdropping, con-dentiality
arises as a challenging issue especially for future wireless networksbecause of their unique …

Considering an OFDM modulation based system including one pair of legitimate
transceivers and one eavesdropping node, we design a physical layer security transmission …
