Abstract
In this paper, a novel and efficient scheme for jamming the Universal Mobile Telecommunications System (UMTS) signal without the assistance from the base station or operator is proposed and evaluated. The scheme is based on new orthogonal multi-sequences developed in this paper. These sequences are specially designed to interfere all the Orthogonal Variable Spread Factor (OVSF) codes that are used in the UMTS transmission and thus, any signal spread by these multi-sequences will interfere all the transmitted data channels at the same time. A power gain of about 7 dB is obtained with respect to the traditional jamming method based on high power wide-band noise injection can be obtained when no channel is used and 10.4 dB in a more realistic scenario with multipath Rayleigh channel.
