An Investigation on Narrow Band PLC-Wireless Parallel Channel Capacity

This work aims to investigate achievable data rate of a hybrid narrow band (NB) communication system composed of Power Line Communications (PLC) and wireless channels.With this regards, we present the equations of channel capacity when using only a linear and time invariant (LTI) PLC, linear and time varying (LTV) PLC or wireless channels. Therefore, the parallel use of PLC-wireless channels capacity is deduced. Results of PLC-wireless achievable data rate are shown when both PLC and wireless channels use optimal power allocation. Furthermore, we show that the parallel use of PLC and wireless channels always present a better achievable data rate than the sole use of PLC or wireless channels.
