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 squarewave matched filter is close to the oversampling ratio

which is far less than that of the traditional root-raisedconsine matched filter. In addition

simulations result of bit-error-rate performance indicate the effectiveness of the proposed square-wave matched filtering.
