Performance of a Chaotic Binary Sequence Based Multiple- Access DCSK Communication System

摘要：

A new kind of multiple-access differential chaos shift keying (MA-DCSK)is presented.It is based on chaotic Binary sequence and Walsh codes,for convenience,we call it BW-MA- DCSK.In the proposed BWMA-DCSK system,the signals that come from the transmitter and the corresponding receiver are multiplied with the same Walsh codes.Due to the Walsh codes orthogonality and the constant instantaneous power of the chaotic binary signal,the interference between users will be greatly reduced.So,the BWMA-DCSK is capable of access ability.The system s bit error rate (BER)performance is analyzed and compared with that of other kind of MA-DCSK. The BER formula is evaluated and the simulation results match the numerical ones well which support the theoretical analysis.
