Robust and reduced-rank UWB receiver for green and smart home communication based on power line

The introduction of smart grids concepts into the electric power systems is pushing forward R&D activities to offer new communication technologies that are capable of dealing with the needs and demands of the electric energy sector. In this regard, this paper discusses and analyzes the performance of robust and reduced-rank based ultra wide band receiver (UWB) for low bit-rate data communication transceivers for smart and green home applications. The main advantage of the robust and reduced-rank UWB receiver is the computational complexity reduction compared with traditional ones. The simulations, based on indoor channel measurements, indicate that the performance losses due to the use of this kind of UWB receivers is lower than 2 dB and, therefore, can be handled by applying a better coding scheme. Finally, the performance of the robust reduced-rank UWB receiver can offer a good performance under impulsive noise presence.
