Adaptive Modulation and Coding Technique Under Multipath Fading and Impulsive Noise in Broadband Power Line Communication

Power line 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 power line communication.
