Abstract

Due to the various navigation signals and wide processing bandwidth, high resolution is required for the narrow band interference estimation in multi-system navigation receiver. The parametric spectral estimator especially the autoregressive (AR) model estimator is used to make high resolution compared to the conventional non-parametric spectral estimator. The properties of both methods are discussed. Based on them, comparison of numerical simulation is done and the asymptotic performance is well addressed. It is shown that the AR spectral estimator is more powerful in estimating narrow band interference for the application of multi-system navigation receiver.
