| Abstract | A telecommunication solution for rural areas is always a big challenge. The problem is usually the high cost for setting up a new communication network in rural areas. Covering rural areas by conventional communication methods such as copper cable, wireless access and fiber optic may not be efficient in installing cost. On the other hand, powerline communication (PLC) can be a good method for information transmission in many rural areas. In this thesis, the power-line communication system is studied and BER performance of the proposed PLC network used as communication medium for rural areas has been investigated over different types of the channels. A set of modulation schemes (DQPSK, 16DPSK, 4QAM and 16QAM) is selected and investigated under difference channel conditions and with different numbers of houses. Simulated with different modulation schemes, each channel is selected a modulation scheme achieving the best BER performance. DPSK is used as a suitable modulation scheme for low speed channels but QAM is better chosen for high speed channels. An investigation of BER performance of the same type of the link with different lengths is also done. The BER performance degradation of PLC channels with increasing number of houses in the network is also investigated. With different topologies, performance of the links is very different. A performance comparison between the link in the residential area with equidistant row houses and one in the residential area without the regular network structure is considered. Simulations are carried out for many types of channels and with many modulation schemes. As shown in simulation results, performance of the links in the PLC network significantly depends on channel characteristics, the length of the link, and the modulation scheme for each link. |
