FPGA design considerations for non-orthogonal FDM signal detection

A fundamental resource in all communication systems and especially in wireless networks which comes at a premium is capacity. While there is a myriad of external factors influencing system capacity, one of the key issues is spectrum availability. Researchers around the globe are therefore constantly trying to invent novel spectrally efficient techniques to improve bandwidth efficiency. SEFDM is an example of such a technique, which promises to yield significant bandwidth gains.
