Optimum Spectrum Extension for PAPR Reduction of DFT-s-OFDM
Renaud-Alexandre Pitaval, Fredrik Berggren, Branislav M. Popovic
Uplink coverage in cellular networks is constrained by the maximum UE transmit power, making peak-to-average power ratio (PAPR) reduction essential. While DFT-s-OFDM with frequency…
Accumulative Iterative Codes Based on Feedback
Alberto G. Perotti, Branislav M. Popovic, Anahid R. Safavi
The Accumulative Iterative Code (AIC) proposed in this work is a new error correcting code for channels with feedback. AIC sends the information message to the receiver in a number…
Deep Extended Feedback Codes
Anahid Robert Safavi, Alberto G. Perotti, Branislav M. Popovic +2
A new deep-neural-network (DNN) based error correction encoder architecture for channels with feedback, called Deep Extended Feedback (DEF), is presented in this paper. The encoder…
Zero Correlation Zone Sequences With Flexible Block-Repetitive Spectral Constraints
Branislav M. Popovic, Peng Wang, Fredrik Berggren +1
A general construction of a set of time-domain sequences with sparse periodic correlation functions, having multiple segments of consecutive zero-values, i.e. multiple zero correla…
Spectrally-Precoded OFDM for 5G Wideband Operation in Fragmented sub-6GHz Spectrum
Renaud-Alexandre Pitaval, Branislav M. Popović, Medhat Mohamad +2
We consider spectrally-precoded OFDM waveforms for 5G wideband transmission in sub-6GHz band. In this densely packed spectrum, a low out-of-band (OOB) waveform is a critical 5G com…
