Abstract
Nowadays, the use of multiple-input multiple-output (MIMO) concepts is being investigated to improve performance of power line communication (PLC) systems, however few attentions have being put on how it can be applied to improve narrow-band technologies based upon single-carrier (SC) modulation. In this paper, a multiple-input single-output (MISO)-SC system for narrowband PLC is devised and the applicability of feedback channel information into the MISO-SC system is considered. Simulation results with outdoor PLC channels and additive noise composed of background and impulsive components indicate that the MISO-SC system with partial feedback channel information can surpass the performances of MISO-SC without feedback and SISO-SC system with and without feedback channel.
