In this paper we consider a K-user fading multiple access wiretap channel, where each user
wants to transmit a message confidentially. There is a passive eavesdropper (Eve) at the …

It is commonly known that physical layer security is achieved with a trade-off in terms of the
achievable rate. Hence, security constraints generate rate losses in wiretap channels. To …

The performance of next-generation wireless systems (5G/6G and beyond) at the physical
layer is primarily driven by the choice of digital modulation techniques that are bandwidth …

In this paper, we address the problem of distributed power allocation in a K user fading
multiple access wiretap channel, where global channel state information is limited, ie, each …

A general communication network can be modeled as an interference channel, wherein
multiple transmitters communicate with multiple receivers. With the inclusion of the Internet …

In this paper, we study a K-user fading multiple access channel (F-MAC), with and without
an eavesdropper (Eve). In the system without Eve, we assume that each user knows only its …

Security constraint results in rate-loss in wiretap channels. In this paper we propose a
coding scheme for two user Multiple Access Channel with Wiretap (MAC-WT), where …
