| 摘 要： | 针对电力系统传感器网，设计了一种方波匹配滤波器，相比传统根升余弦匹配滤波器大大降低了实现复杂度。一方面方波匹配滤波器省去了传统方法中的乘法运算；另一方面，方波匹配滤波器的长度接近过采样倍数，远小于传统根升余弦匹配滤波器的长度。此外，误比特率性能仿真结果也表明了方波匹配滤波的有效性。

| Abstract: | A square-wave matched filter is designed for sensor network of electric power systems,which greatly reduces implementation complexity compared with traditional root-raised-consine matched filter. On one hand, square-wave matched filter saves multiplication of traditional method;on the other hand,the length of the square-wave matched filter is close to the oversampling ratio,which is far less than that of the traditional root-raised-consine matched filter. In addition,simulations result of bit-error-rate performance indicate the effectiveness of the proposed square-wave matched filtering. |
