摘　　要：针对高速高动态宽带卫星信道中线性失真和非线性失真并存的问题,提出一种基于新型级联结构的宽带非线性盲均衡算法。算法通过构建一种线性与非线性级联的滤波器算法结构,以同时矫正宽带卫星信道带来的线性畸变和非线性畸变。为验证算法的有效性,在10 Gbit/s高速数传接收机平台进行了实验。实验结果表明,相比传统的线性均衡算法,该算法可以同时矫正信道的线性畸变和非线性畸变,工程应用价值高。To address the problem of coexistence of linear and nonlinear distortion in high-speed and high-dynamic wideband satellite channels,a wideband nonlinear blind equalization algorithm based on a novel cascade structure is proposed.The proposed algorithm can simultaneously correct the linear and nonlinear distortion caused by a wideband satellite channel by constructing an extended cascade structure of FIR linear filter and nonlinear function.In order to verify the effectiveness of the algorithm,experiments are carried out on a 10 Gbit/s high-speed data transmission receiver platform.Experimental results indicate that compared with the conventional linear equalization algorithm,the proposed algorithm can correct both linear and nonlinear channel distortion,and has high engineering application value.
