| Abstract(in English) | Suppression of narrow-band interference (NBI) in direct-sequence code-division multiple access (DS CDMA) system using a lattice-based adaptive infinite impulse response (IIR) notch filter is studied. A simplified normalized coefficient update algorithm that requires no gradient signal generating filter is proposed. Convergence behavior of the algorithm is shown not to vary much with the number of users for a tone NBI model. Closed form expression for the SNR improvement at the pseudonoise (PN) correlator input is derived. Computer simulations are shown to verify the analysis and compare the performance of the proposed NBI suppression scheme with linear predictor. |
