ABSTRACT OF THE DISCLOSURE A power line communication system specially designed for use in local area network (LAN) configurations has receiver and transmitter sections for fast, highly reliable data communi- cation. The receiver includes controlled adaptive second order filters for ensuring data reception in virtually any signal environment having noise and distortion characteris- tics, especially alternating current (AC) power lines. A wideband phase shift-keyed (PSK) carrier is impressed on the the transmission medium, the carrier having power spread approximately uniformly across a useful frequency bandwidth. A transmitter section is arranged for adaptive feedback control of the transmitted signal power, so as to prevent possible damage to the transmitter when the transmission medium impedance is low. A logic control circuit provides a correlation count of a received signal in comparison with a known reference signal in order to effectively achieve phase synchronization between the receiver and transmitter.
