中文摘要	It is an effective approach to enhance the performances of multi-user communication systems over power distribution networks if the potential resources of the network are fully utilized and the characteristics of the channel are optimized. We firstly define the typical multi-user communications over the three-phased power distribution networks-multi-access (MA), broadcast (BC) and interference (IC) channels. Then the vector channel models as well as the decomposing vector channel into the scalar channel are described. A novel algorithm to calculate the optimal distribution of input power and bit rate for the vector channel is presented in which the optimal destination is set to get the maximum bit-sum rate of every scalar channel. Based on the normalized measurement channel model, the bit rate and input power distribution of MA and BC are calculated using the algorithm, the results show that multi-user communication utilizing the three-phase power lines and the vector dynamic spectrum management provide a new solution to the power distribution network communications.
