仿真分析表明，交换算法在平稳信道环境中，运算速度快且能够保证分配结果的最优性。
The simulation results show that the bit swap algorithm rapidly and optimally reallocates the bits and power between sub-carriers for a time stationary power-line channel.
前者是通过对载波信道的频率特性时变性测试、分析，实现信号平稳传输。
The former realizes steady transmission of signal by testing and analysing the carrier channel's frequency characteristic .
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。
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.
