| 20130335207 | POWERLINE COMMUNICATION DIVERSITY COUPLING TECHNIQUE - A powerline communication diversity coupling mechanism may implement a transformer coupling unit. The transformer coupling unit can receive a communication signal to be coupled to a plurality of powerline communication channels for transmission in a powerline communication network. The transformer coupling unit can split the communication signal into a plurality of communication signals for transmission. The transformer coupling unit can couple each of the plurality of the communication signals to a corresponding one of a plurality of the powerline communication channels for transmission in the powerline communication network. Also, the transformer coupling unit can receive a plurality of communication signals on each of a plurality of powerline communication channels. The transformer coupling unit can combine the plurality of the communication signals into a communication signal. The transformer coupling unit may then couple the communication signal to an analog front end and other processing units for processing the communication signal. | 12-19-2013 |
