Protocol Coding Through Reordering of User Resources: Applications and Capacity Results

While there are continuous efforts to introduce new communication systems and standards, it is legitimate to ask the question: How can one send additional bits by minimally changing the systems that are already operating? This is of a significant practical interest, since it has a potential to generate additional value of the systems through, for example, introduction of new devices and only a software update of the access points or base stations, without incurring additional cost for infrastructure hardware installation.
