标题： A Digital Matched Filter for Reverse Time Chaos

摘要： 利用反向时间混沌可以实现硬件混沌系统，这些系统可以在与现有最先进水平相当的速度下运行，同时需要显著更简单的电路结构。 由于反向时间系统表现出由线性基脉冲部分形成的闭式解，因此可以对反向时间系统进行匹配滤波解码。 已经计算出系数，并用于将匹配滤波器数字实现为有限脉冲响应滤波器。 数值仿真证实了这正确实现了可用于检测混沌信号的匹配滤波器。 此外，该滤波器的直接形式已在硬件描述语言中实现，并且其性能与数值结果一致。 显示英文摘要

摘要： The use of reverse time chaos allows the realization of hardware chaotic systems that can operate at speeds equivalent to existing state of the art while requiring significantly less complex circuitry. Matched filter decoding is possible for the reverse time system since it exhibits a closed form solution formed partially by a linear basis pulse. Coefficients have been calculated and are used to realize the matched filter digitally as a finite impulse response filter. Numerical simulations confirm that this correctly implements a matched filter that can be used for detection of the chaotic signal. In addition, the direct form of the filter has been implemented in hardware description language and demonstrates performance in agreement with numerical results.
