Powerline communication is a communication technology that uses the powerline to send or receive data. The research was developed to provide a deeper understanding about the environment of the powerline channel. Thus, the researchers developed a broadband powerline channel emulator that can emulate the behavior and characteristics of the power line. This research aims to implement the indoor broadband power-line channel emulator on a field programmable gate array (FPGA). In addition, the study uses Zimmermann's channel model as its transfer function. Through the hardware implementation, the researchers were able to obtain the signal that was being sent at the input, except that the magnitude of the output was much smaller due to the injection of noise and the incorporation of the transfer function. The analysis of noise and transfer function were done through MATLAB and XILINX simulations. Through these simulations, the researchers were able to obtain the root mean square (RMS) delay spread and compare the delay between the software simulation and hardware implementation. Also, the signal-to-noise ratio (SNR) of the system was also obtained through the use of the R3131A Advantest Spectrum Analyzer.
