由ParlitzU和ErgezinerS提出的鲁棒通讯方法要求发射器和接收器产生完全相同的混饨序列，这在实现上是有困难的．本文改善了这一方法．改善后的方法不仅对外噪声是鲁棒的，而且适合于实现． Robust communication methods proposed by Parlitz U and Ergeziner S require that the transmitter and receiver produce exactly the same chaos sequence, which is difficult to implement. This article has improved this method. The improved method is not only robust to external noise, but also suitable for implementation.
