Patent ID: 8908491

Claim:
A method for assessing the feasibility of a sub-carrier of a Broadband Power Line (BPL) signal, particularly for avoiding the mutual influence of the BPL-signal and an additional signal, with the BPL-signal comprising a plurality of sub-carriers and with one symbol each able to be transmitted in the sub-carriers, comprising the steps: extracting a received value y[k] of the BPL-signal received from a sub-carrier wherein k is an integer; equalizing the received value y[k] using an assessed transmission function Ĥ of a transmission channel; determining a symbol {circumflex over (d)}[k], which is coded in the received value y[k]; distorting the symbol {circumflex over (d)}[k] with an assessed transmission function CI of the transmission channel, said distorting of the symbol {circumflex over (d)}[k] resulting in a processed signal {circumflex over (d)}[k]·Ĥ; forming a difference between the received value y[k] and the processed signal {circumflex over (d)}[k]·Ĥ; and deciding about the feasibility of the sub-carrier based on the difference y[k]−{circumflex over (d)}[k]·Ĥ.
