A Novel IBF and Its Application in Ultra-Wideband Systems

This paper proposes a new interleaving rule, with which a new IBF (IBF, intertwined bridge function) is generated. Not only does the new intertwined bridge function have a zero correlation zone, but also its cross-correlation performance is ideal. An ultra-wideband system is introduced, which uses the intertwined bridge functions as the spreading code. The sequence of interleaved bridge function with zero autocorrelation bridge area and zero cross-correlation zones can better reduce multiple access interference and multipath interference. It is shown by the simulation results that the ultra-wideband systems using the interleaved bridge function as the spreading sequence have better error rate performance.
