Title
Interference rejection in DS/SS-systems with an improved RLS-whitening filter.
Abstract
The Huber m-estimation principle is applied, in a simple way, to improve interference mitigation capability of the recursive least squares (RLS) whitening interpolation filter, implemented either in the basic or linear phase form. The simulation results show that in the code phase estimation the robust linear phase RLS interpolation filter mitigates interference more than the regular RLS and linear phase RLS interpolation filters, especially if the bandwidth of the interference is narrow (< 25 %) when compared to the bandwidth of the used direct sequence signal. It is also shown that whitening does not significanty decrease the code phase estimation accuracy of the matched filter estimator.
