论文摘要
在这项工作中，我们扩展了一类已知类别的基于混乱的编码调制（CCM）系统的可能性，以解决高功率放大器（HPA）非线性的问题。假设是，可以利用CCM非线性性质来抵消其对系统性能的影响，从而避免需要前延伸器。我们为CCM的设计提出了一种优化方法，以证明这一假设。结果表明，对于给定的后退级别，可以设计基于混乱的编码器和解码器的非线性映射函数，以补偿HPA对错误率的影响。
In this work we expand the possibilities of a known class of chaos-based coded modulation (CCM) systems to address the problem of high-power amplifier (HPA) nonlinearity. The hypothesis is that the CCM nonlinear nature can be exploited to counteract its effects on the system performance, avoiding the need of a predistorter. We propose an optimization method for the design of the CCM to prove this hypothesis. The results show that, for a given back-off level, a nonlinear mapping function for the chaos-based encoder and decoder can be designed to compensate the HPA effect on the error rate.
