Abstract
A system and method for detecting power line null frequencies and for adjusting the transmit frequency and transmit power to maximize the reliability and efficiency of the AC power line transmission link is described. This invention uses a programmable logic device in the transmitter, which transmits multiple frequencies to a receiver. The receiver detects and records the bit error rate and/or the received noise per frequency and communicates this information to the transmitter. When all desired frequencies have been transmitted and tested, the optimal frequency is identified or selected. Generally, the optimal frequency is the frequency requiring the lowest transmit power while maintaining an acceptable bit error rate or an acceptable noise level.
