Previous work on this problem has typically assumed that the channel conditions between the base station and the users are governed by a stationary stochastic process.
在此问题上，以前的研究工作中一个经典的假设是基站与用户之间的信道条件变化为一平稳随机过程。

This algorithm doesn't need priori knowledge or reference channel, and it can be used in the stationary or nonstationary noise environment.
该算法无需先验知识和参考信道，且对平稳或非平稳噪声均适用。

The imaginary vibration model of transition state is studied chiefly, and points to reactant and product, and illuminates that stationary points locate the right reaction channel.
