摘要: We consider a physical layer approach to enhance wireless security by using the unique channel state information (CSI) of legitimate user authenticate subsequent transmissions from this user, thereby denying access any spoofer whose CSI would significantly differ that virtue different spatial location. In some existing approaches, multicarrier systems have been considered where frequency response at distinct frequencies is used devise hypothesis testing approach: current transmission (packet) same as previous transmission? paper we investigate single-carrier timedomain via either residual or time-domain comparison. A formulated test whiteness residuals are generated estimated transmission. also compared with Two binary approaches and illustrated simulations.
