Abstract:

With IMT-Advanced standardization process developing，research of time division dual technology has become one of important means which utilize and extend Chinese existing technologies.For long term evolution frame structure 2，paper on the basis of time division dual channel reciprocity proposes a linear channel prediction model based on minimum mean squared error.Meanwhile，it simulates and compares the performance under different speeds of single frame recursive channel prediction and multi-frame recursive channel prediction.

Key words: time division dual, channel reciprocity, channel prediction
