| چکیده | ||
| This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the third method the relay tries to maintain the robust soliton distribution by favoring the first degree packets. Simulation results demonstrate that the use of LT codes in a network can significantly improve the system performance and reduce the overhead both in presence and in absence of impulsive noise. Also it is investigated that the first method outperforms the two ones but it has a higher complexity at the relay node. | ||
