We derive a mathematical expression called interference suppression factor of twosided 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.
