Assessment of polarization codes in nonstationary channels
摘要
Abstract
The polarization code is a new channel coding method based on the phenomenon of channel polarization.Up to now,most of researches on polarization code are devoted to the applications of polarization codes in stationary channels.In this paper,the research on polarization codes is applied to nonstationary channels,in which Monte Carlo method should be used for it.The variation of crossover probability of the special binary symmetric channel (BSC) is regarded as the sine function distribution.According to numerous experimental results,it is found that the phenomenon of channel polarization still exists when polarization codes are applied to nonstationary channels,but the polarization phenomenon is not so obvious as that when polarization codes are applied to stationary channels.关键词
