| Abstract: | Remote meter reading system is very important for the development of smart grid and data acquisition automation.But at present stage,the remote meter reading is usually vulnerable to the impact of transmission medium.This paper presents a QPSK communication system based on remote meter reading system and analyses the system performance.With the characteristic that the system BER decreases while the signal noise ratio increases,smart meter reading is realized.It helps power utilities reduce the cost and impr... |
