Abstract: In order to accurately evaluate the bit error rate(BER) of DSUWB systems with narrowband interference suppressor, a method based on characteristic function (CF) is proposed for precisely calculating the BER of DSUWB systems using twosided transversal filters for rejection of single tone interference. We derive a mathematical expression called interference suppression factor of twosided transversal filters. In addition, theory analyses show that with sufficiently large tap number, the tone interference could be almost cancelled totally. The simulation and numerical results validate the accuracy and effectiveness of analytical BER derivations.
