Performance of simplified Faster-than-Nyquist tranceiver

As OFDM has become the basis of many of telecommunication standards due to its ease of implementation, stability and efficiency, Faster-than-Nyquist signaling became an interesting base for envisioned telecommunication breakthrough, since it is based on an already used and successfully implemented technology which is OFDM, and it inherently obtains the legacy system merits, at the expense of system complexity. In this article we introduce signaling over none orthogonal carriers with a controllable orthogonality factor that optimizes channel usage based on channel quality feedback, with agility to cope with varying channels with rate higher that OFDM can tolerate.
