M-ary Frequency Shift Keying (MFSK) using one or more orthogonal tones per symbol has been in use in noncoherent systems for quite some time. We present an alternate system for non-coherent systems using non-orthogonal tones, spread non-uniformly throughout the bandwidth which outperforms the equivalent orthogonal tone system. We demonstrate that from a theoretical capacity point of view, the same...
