Abstract: Discrete Fourier transform (DFT) modulated filter banks (FBs) are considered as strong tools used to implement both dynamic spectrum access and spectrum sensing in cognitive radio (CR) systems. High time-frequency (TF) resolution for spectral estimation and effective spectrum access with low complexity transceivers are the basic objectives in CR sy... Show More

This article belongs to the Special Issue 5G Wireless Communication Systems

Abstract: Different from other Coding, based on the Overlapped Multiplexing Principle discovered by author， a novel OVTDM (Overlapped Time Division Multiplexing) Waveform Coding is proposed. Instead of the encoding matrix and mapped signal constellation, any engineering sense band-limited Multiplexing Waveform can be employed. By its data weighted shift over... Show More
