Abstract

For these communication systems whose transmitted waveforms have a much closed signal space, such as the attractive Ultra Narrow-band (UNB) modulation technology, it is rather toilsome to obtain the satisfactory performance because of the difficulty in accurately determining the threshold of the optimum receiver, which is mainly caused by its tiny waveform dipartition as well as the unruly DC variant. To response this realistic challenge, a novel nonlinear transform in receiver has been proposed in this paper. It is demonstrated that our presented scheme can indeed improve the BER performance of the Ultra Narrow-band system.
