Errors are integral part of every communication system, whether wired or wireless. There are two broad approaches to deal with errors: Detection and discard of data elements in error and optional recovery from such errors either through proactive or reactive (re)-transmissions. Both these approaches assume that errors are binary in nature, i.e., an error in transmission implies a need to discard or recover the erroneous bits. In this paper, the authors consider an intriguing alternative, one in which data elements in error are accepted as "Approximately correct" values. They call this approximate communication. More specifically, they intro-duce the notion that data elements being received are not just correct or incorrect.
