Abstract

Abstract

An adaptive NarrowBand Interference (NBI) suppression approach is proposed for DS-UWB systems. Based on the equivalence between the objective function optimization and linear equations, the proposed scheme translates the optimization model into linear equations and then performs adaptive filtering by employing an effective iterative method for linear equations, namely Conjugate Gradient (CG) algorithm. Theoretical analysis and simulation results show that, compared with the traditional NBI mitigation schemes, the proposed scheme can achieve a superior performance-to-cost ratio, and therefore can be considered as a compromised candidate for low cost, low power consumption and low complexity indoor UWB application scenarios.
