中文摘要：

考虑由Rosenblatt过程驱动的Omstein-Uhlenbeck过程X1=X0-θ∫0^tXsds＋σZt^H的最小二乘估计。其中Zi^H是一个指数为H∈（1／2，1）的标准Rosenblatt过程，参数θ，σ〉0。在σ已知并且过程可以被连续观测的情况下，研究未知参数θ的最小二乘估计。

英文摘要：

In this paper,we investigated the least squares estimation of the Ornstein-Uhlenbeck process X1=X0-θ∫0^tXsds＋σZt^H, driven by Rosenblatt process,where Zi^H was a Rosenblatt process with Hurst index H ∈ （1/2,1） 0 and θ,σ〉0 were two parameters. When σ was known,we studied the least square estimator of the parameter θ under the continuous observation.
