Using this technology there is no need of new installation which is advantageous compared to other technologies. However, due to noises and multipath fading in BPLC systems, studies on coding techniques and suitable modulation schemes are unavoidable. Studies by other researchers have shown that multicarrier modulation techniques perform better than single carrier modulation techniques in power-line channels. In this work multicarrier spread spectrum (MC-SS) has been adopted as a modulation scheme. This work has investigated the performance of channel coding in power-line channel. Due to their application in digital communication systems, the coding techniques considered in this work are BCH codes, Reed-Solomon codes, Convolution codes, Concatenated codes and the Low density parity check codes. The Generalized transmission line (TL) theory model developed by Anatory et al has been adopted. A typical power-line network found in Tanzania has been adopted and subjected to different coding techniques in a typical noise environment. It has been found that the coding gain of 16dB, 10dB, 6.5dB, 5.5dB and 4.5dB have been realized using LDPC, RS, Concatenated, Convolution and BCH codes respectively at BER of 10-6. This implies that LDPC is appropriate coding technique for BPLC systems.Coding techniquesDigital communicationBroadband power line communicationBPLCPower line communication channelPower line channelsChannel codingMulticarrier spread spectrumMC-SSDissertation
