Jammer suppression in spread spectrum

This paper addresses the performance evaluation of the suppression of a real single tone jammer using singular valve decomposition (SVD). A system model employing the proposed SVD-based technique to reject the single-tone jammer in a direct sequence binary phase shift keying (DS/BPSK) spread spectrum system is presented. The performance of this system is based on the BER results obtained through simulations. The results are shown to compare favorably to those obtained by the conventional two-sided transversal filter method, especially when the jammer power is more dominant.
