Abstract:Power-line networks are great candidates for broadband communication systems. However, a power-line channel suffers from multipath effects, and impulsive noise due to harsh environment in the network. This study attempts to overcome these obstacles and increase the-bit-error-rate performance by using adaptive modulation and coding. Additionally, the multiple wires allow the communication via more than one channel. Thus, multiple-input multiple-output communication system can be utilized in the powerline. In this study QPSK, 16-QAM, and 64-QAM schemes and turbo coding at 1/2 and 3/4 coding rates; SISO, 2x2, and 3x3 MIMO channels are used. As a result, it is observed that adaptive modulation and coding techniques perform better than fixed modulation schemes under multipath fading and impulsive noise both for SISO, and MIMO channels in broadband power-line communication. Additionally, it is found that the bit-error-rate performance is increased by using spatial multiplexing technique in powerline communication.
