Achieving High Data Rate in Multiband-OFDM UWB Over Power-Line Communication System

Theoretical studies indicate that a transmission data rate of up to gigabits per second can be achieved over low-voltage (LV) indoor power-line cables. Achieving a very high data rate (up to 480 Mb/s) is expected by applying WiMedia multiband-orthogonal frequency-divison multiplexing (MB-OFDM) standard for wireless ultra-wideband (UWB) communication over the power-line channel. However, the viability of this concept needs to be tested experimentally. This paper presents a novel design of demonstration system for the UWB over power-line communication technology. The demonstration system consists of an MB-OFDM UWB kit and is capable of transmitting very high data-rate signals over the LV power-line cables. It provides means to evaluate the performance of the UWB over power-line communication systems and analyze its viability in actual home networking scenarios.
