Additionally, it provides inherent physical layer security using the Zero-forcing (ZF) precoding technique. However, the channel becomes vulnerable to eavesdropper (Eve) if the channel impulse response is assumed to be time-invariant or stationary through coherent block intervals. In this paper, a physical layer secure scheme is proposed based on phase index RSM to combat eaves-droppers that use k-nearest neighbors (KNN) supervised pattern recognition. The average bit error rate (BER) performance shows the ability of the proposed scheme to provide a suitable level of security while degrading the average BER performance of Eve.eninfo:eu-repo/semantics/embargoedAccessMulti-Input Multi-OutputK-Nearest Neighbors (KNN)Zero-Forcing PrecodingSupervised Pattern RecognitionReceive Spatial ModulationPhysical-Layer SecuritySupervised Pattern RecognitionConference Object10.1109/WCNC49053.2021.9417120N/AN/A
