摘　　要：为了满足在额定功率有限的情况下,传输速率最大化。选择在低压宽带电力线信道条件下,分析2 MHz^100 MHz的宽带电力线信道特征与参数。利用已有电力线信道模型,通过迭代分块约束注水算法对电力线通信进行动态子载波分配,相比传统的注水算法,改进之后的算法能更好的根据电力线信道约束条件给子载波分配功率,得到更优的信道容量。In order to maximize the transmission rate with the certain rated power,this paper analyzes the channel characteristics and parameters of 2 MHz?100 MHz broadband power line communication under the condition of low-voltage pow_er line communication channel.The iterative block constraint allocation algorithm can dynamically allocate subcarrier of power line communication through using the existed power line communication channel model.Compared with the traditional water injection algorithm,the improved algorithm can better constraint for subcarrier allocation according to the power line communication channel power and get better channel capacity.
