METHOD AND DEVICE FOR TRANSMITTING INFORMATION OVER A COMMUNICATION CHANNEL WITH VARIABLE IMPEDANCE, IN PARTICULAR FOR A SIGNAL CONVEYED BY POWER LINE COMMUNICATION |
摘要 |
A method includes digital/analog conversion of a digital signal modulated by information to provide a modulated initial analog signal having a crest factor greater than one, and amplification of the initial analog signal to provide an amplified modulated signal. A modulated channel analog signal derived from the modulated amplified analog signal is transmitted over a communications channel, with impedance of the communications channel varying during the transmission. The method further includes at least one determination during the transmission of a peak-clipping rate of the amplified analog signal over at least one time interval, and an adjustment of a level of the initial analog signal as a function of the determined peak-clipping rate. |
