摘要 为克服信道噪声、系统参数误配及用户串音对混沌通信系统的影响,本文在无先导卡尔曼滤波器(Un-scented Kalman Filter,UKF)算法的基础上,提出了一种有反馈结构的滤波器阵列及相应的滤波算法,以实现多用户的混沌通信.仿真结果表明,在单信道的多用户通信环境下,该滤波器阵列算法有较快的收敛速度,并能有效地实现多用户的混沌通信. In order to reduce effectively channel noise, parameter mismatch, and cross talks in a single channel＇s communication systems with chaos, a feedback filter-bank and its algorithm based on the unscented Kalman filter are proposed for implementing multiuser communications with chaos. The results by computer simulation indicate that the algorithm has a faster convergence speed and can realize effectively multiuser communications in a single channel.
