Methods and systems for applying an improved interleaver for modems operating on power grid
Methods and systems are disclosed for applying an interleaver that better distributes signal errors to be used in devices operating on low voltage power grids. One embodiment of a method comprises: determining a frequency cycle of the communication medium; setting an interleaver block size based on the frequency cycle of the communication medium; re-arranging bits in a data packet based on the interleaver block size; transmitting the re-arranged data packet over the communication medium to a receiver. Specifically, according to an embodiment, the interleaver block size is set to one-half of the frequency cycle of the communication medium.
