Abstract:
In modern spread spectrum communications, how to generate spread spectrum sequence quickly is important in system modeling and design and therefore has received wide attentions. Accordingly, this study investigates the fast generation of Bent sequences, where we use a single generator to generate multiple Bent sequences simultaneously and therefore significantly reduce the realization cost. The proposed fast generator comes from the intrinsic relations between the m-sequence and the Bent sequence, i.e., the m-sequence and its shift versions can construct a trace based generator of Bent sequence family with sequence number approaching 2n/2. Moreover, we realize such fast generators in Agilent ADS (Advanced Design System) 2005A software and two examples are provided: four order Bent sequence and twelve order Bent sequence. Then, both fast generators are verified by comparing the simulated autocorrelation and crosscorrelation with the corresponding theoretical values and the results prove that the proposed method is effective and beneficial for spread spectrum communications.
