用于高频谱效率的通信的自适应非线性模型
摘要：
接收机可操作以使用可以合并非线性模型的序列估计处理生成发送码元的估计。接收机可以基于可以指示所述发送码元所经历的非线性的特定通信信息适配所述非线性模型。接收机可以从所述发送码元的估计生成重构信号。接收机可以基于从所述重构信号生成的误差信号的值适配所述非线性模型，并且可以从所生成的估计中可以对应于已知码元和/或信息码元的一部分生成所述误差信号的值。可以在适配算法中对对应于已知码元的误差信号的值赋予较大权重，并且可以在适配算法中对对应于信息码元的误差信号的值赋予较小权重。
摘要（英）：

A system may comprise circuitry that includes a sequence estimation circuit and a non-linearity modeling circuit. The circuitry may be operable to receive a single-carrier signal that was generated by passage of symbols through a partial response filter and through a non-linear circuit. The circuitry may be operable to generate estimated values of the symbols using the sequence estimation circuit and using the non-linearity modeling circuit. An output of the non-linearity modeling circuit may be equal to a corresponding input of the non-linearity modeling circuit modified according to a non-linear model that approximates the non-linearity of the non-linear circuit through which the received signal passed.
