| Abstract |
Recently, there a lot of activities on the researches that implement many kinds of control system using power lines. To implement that, it is desirable to use hybrid PSK model because it takes advantage of PSK and DPSK which has a low-bit-error rate. In this parer, we implement the transmitter of this model. Because the power line is not designed for the data communication, we separated the signal generator circuit and the signal loading circuit so that minimized noises from outside. Also, to make it easy on the experiments, most of process are performed by software. As a result, transmitting a high frequency signal on the power line made no effects on the electrical devices. |
