Özet

Poweline networks are a great candidate for broadband

communication systems. However, a power-line channel

suffers from multipath effects, and impulsive noise due to

changing load in the network. This paper attempts to

overcome these obstacles and increase the bit error rate

performance by using adaptive modulation and coding. In

this study QPSK, 16-QAM, and 64-QAM schemes and turbo

coding at 1/2 and 3/4 coding rates are used. As a result, it is

observed that adaptive modulation and coding technique

performs better than fixed modulation schemes under

multipath fading and impulsive noise in broadband powerline

communication.
