Abstract/Summary

In this dissertation, a power line communications channel (PLC) emulator that has a random selectivity feature to mimic real-world PLC scenario applied to an indoor network has been designed, developed, tested, and evaluated. The emulator has been implemented in FPGA-based hardware. State-of-the-art PLC channel emulators do not have a random selectivity feature when generating the channels and most of them emulated either the channels only, or the noise only. In this dissertation, the emulator emulates various PLC channels and noise. The performance of the emulator has been compared with the random channel variates generated by PLC channel models. A limiting factor is the number of bits allocated for the fraction part of the fixed-point equivalent of the transfer function.
The results further show that frequency domain operation had effectively speed up the emulation process, and in terms of speed via the number operations per seconds, the developed FPGA emulator is 200% much faster than the simulator.
