Power wireless communication system has received more and more attention in recent years. At present, power wireless communication system has not been applied on a large scale in Shandong Province. With the proposal of ubiquitous power Internet of things (UPIOT), the State Grid Corporation of China (SGCC) is paying more and more attention to the construction of wireless networks. Shandong Province is gradually carrying out the construction of wireless communication networks, with corresponding research undertaken accordingly. This paper mainly studies the channel estimation technology of MIMO based power wireless communication system. According to the movement patterns of the user terminal, we manage to model the downlink channel, as well as give out the channel estimation and the corresponding training sequence design method. The relationship of channel capacity and training sequence length is verified by simulation, and the optimal value of training sequence length under given parameters is obtained. At the same time, the channel training optimization scheme is given by the use of channel correlation, in which the specific parameters are determined by the specific system.
