LTE Physical Layer Vulnerability Test to Different Types of Jamming Signals

This paper presents an analysis of the susceptibility of the LTE physical layer in the presence of jamming signals. Commercial jammers are often characterized by the frequency bands that they cover. The jamming signal generally sweeps quickly and periodically the frequency band, with a fixed sweep period (SP). According to the jammer model, the frequency band, the power and the sweep period can be different. In this communication, we study the potential impact of a jamming signal according to its power and its sweep period in order to analyze the disturbing mechanisms. The quality of the LTE uplink is analyzed through the measurements of three parameters: Error Vector Magnitude (EVM), Occupied BandWidth (OBW) and Adjacent Channel Leakage-power Ratio (ACLR).
