Recently, physical layer security has been recognized as a new design paradigm to provide
security in wireless networks. In contrast to the existing conventional cryptographic methods …

This paper investigates the secrecy rate maximization problem for the multiple-input-single-
output multiple-antenna-eavesdropper (MISOME) wiretap channel with multiple randomly …

Recently, there has been growing interest in secure communication via multi-antenna
physical-layer designs. In this paper, we consider a transmit covariance design for a secrecy …

This paper studies the secrecy rate maximization problem of a secure wireless
communication system in the presence of multiple eavesdroppers. The security of the …

Secrecy transmission is investigated for a cooperative jamming scheme, where a multi-
antenna jammer generates artificial noise (AN) to confuse eavesdroppers. Two kinds of …

This paper investigates the physical layer security in a multiple-input-single-output multicast
channel, where a common message is transmitted to multiple receivers and only statistical …

This paper investigates secrecy rate optimization problems for a multiple-input-single-output
(MISO) secrecy channel in the presence of multiple multiantenna eavesdroppers …

This paper studies different secrecy rate optimization problems for a multiple-input–multiple-
output (MIMO) secrecy channel. In particular, we consider a scenario where a …

In this paper, we study different secrecy rate optimization techniques for a multiple-input–
multiple-output (MIMO) secrecy channel, where a multiantenna cooperative jammer is …

Abstract Systems and methods of friendly jamming for securing wireless communications at
the physical layer are presented. Under the assumption of exact knowledge of the …
