This paper considers a multi-machine control system using power line communication (PLC). The signal-to-noise ratio (SNR) of PLC channels has cyclostationary features synchronous to the mains voltage. As a promising candidate of the multiple access scheme for the system, this latter proposes a synchronous code division multiple access (SCDMA) scheme that uses mains voltage as its system clock. By using orthogonal codes, the communication performance of each code-channel is equalized, and the worst-case performance is improved.
