A Scheme of Combining Differential Chaos Shift Keying with Multiple-Input Multiple-Output System

Applying chaotic digital communication system on wireless channel is a very difficult problem to solve. A new scheme based on Multiple Input Multiple Output (MIMO) system is proposed aiming at improving Bit Error Rate (BER) in chaotic communication. Incorporating Differential Chaos Shift Keying (DCSK) with MIMO could improve the transmission efficiency of chaotic secure communication scheme. Moreover, embedding the DCSK algorithm in the MIMO system could meet the demand of security and transmission efficiency. In addition, making simulation of this algorithm and getting the bit error rate analysis chart could let us know the performance of communication. Testing results show the accuracy and rationality of MIMO-DCSK system, but further study is needed in terms of scalable scheme.
