This paper studies the secure degree of freedom (SDOF) of the multiway relay wiretap system $K$ -user MIMO Y wiretap channel, where each legitimate user equipped with $M$ antennas intends to convey independent signals via an intermediate relay with $N$ antennas. There exists an eavesdropper which is equipped with $N_{e}$ antennas close to the legitimate users. In order to eliminate the multiuser...
In this paper, we study the information-theoretical security of the K-user MIMO Y wiretap Gaaussian channels and deduce the lower bounds of the secure degrees of freedom (SDOF). Due to the different receiving links of the eavesdropper, we propose two MIMO Y wiretap models which are called Broadcast Wiretap Channel (BWC) and Multi-access Broadcast Wiretap Channel (MBWC), respectively. Each legitimate...
This paper analyzes the effect of channel gains on the performance of signal detection in multiple-input multiple-output (MIMO) systems, and based on that proposes an intelligent MIMO signal detection algorithm. It dynamically chooses child-node number according to the gains between antennas. This algorithm is verified by simulation in the MIMO system with Matlab. While keeping the detection performance...
