What is Multi-Carrier Modulation?
Multi-carrier modulation or MCM is an approach to data transmission that involves segregating the data into several more or less equal components. The individual components are then routed across different carrier signals. At the point of termination, the individual components are reassembled and delivered. The actual history of multi-carrier modulation goes back to the middle of the 20th century. At the time, this method of transmitting data was employed by the military arms of the United States and several other countries. The actual process relied on each of the carriers used to route the components to have an narrow bandwidth. This made it possible for the composite broad bandwidth transmission to be broken down into segments or components that could be securely routed and converted back into a single transmission that could be decrypted and understood at the receiving end. Using multi-carrier modulation in this method allowed the military to make effective but secure use of the an
