| Notes | power line carrier communication ; frequency hopping ; OFDM ; gradient search 11-2305/TN This paper propose a novel algorithm for optimizing the performance of frequency hopping OFDM communication network. By taking the location and special distribution of the transmission nodes into consideration, it analyzes the closed-form so- lution of the transmission interrupt probability of the physical interference channel. Furthermore, it use the closed-form solution to characterize the transmission capability of the frequency hopping low voltage power line carrier communication network. In order to optimize the transmission performance, it takes the interrupt probability as the system objective function, and integrates the exhaus- tive search and the gradient search strategies to optimize the number of the frequency hopping channels, the OFDM modulation in- dex and the error control coding rate, which aims at finding out their optimal combination.
