Abstract
A system and method for extending the operating range and/or increasing the bandwidth of a communication link. The communication link may consist of any two communication devices that are connected by two or more separate “band limited” communication paths for the transmission of information therebetween. In operation, the communication devices use a “frequency split scheme” to divide the information transmitted between the devices into two or more signals, each of which is transmitted over one of the communication paths. A “frequency foldback scheme” may also be used to shift the information from the higher frequencies to the lower frequencies of each respective signal, thereby taking advantage of the fact that more information can be carried in the lower frequencies. By using these schemes, it is possible to extend the operating range of the communication link and/or transmit a greater amount of information over the communication paths to thereby increase the bandwidth of the communication link.
