Wideband Direct Satellite Uplink Enabled by Pilot-less Sparse Superposition Codes
Alberto G. Perotti, Branislav M. Popovic, Renaud-Alexandre Pitaval
Direct satellite uplink is severely constrained by limited link budgets, which hinder the exploitation of wideband resources, and ultimately limit the throughout. This paper presen…
Repeated-and-Offset QPSK for Low-PAPR DFT-s-OFDM in Satellite Communications
Renaud-Alexandre Pitaval
Motivated by the convergence of terrestrial cellular networks and satellite communications, this article considers an adaptation of offset quadrature phase shift keying (OQPSK), tr…
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…
DFT-s-OFDM-based On-Off Keying for Low-Power Wake-Up Signal
Renaud-Alexandre Pitaval, Xiaolei Tie
5G-Advanced and likely 6G will support a new low-power wake-up signal (LP-WUS) enabling low-power devices, equipped with a complementary ultra low-power receiver to monitor wireles…
Fastening the Initial Access in 5G NR Sidelink for 6G V2X Networks
Marouan Mizmizi, Francesco Linsalata, Mattia Brambilla +8
The ever-increasing demand for intelligent, automated, and connected mobility solutions pushes for the development of an innovative sixth Generation (6G) of cellular networks. A ra…
A note on simplified SINR expressions for OFDM with insufficient CP
Renaud-Alexandre Pitaval
This note provides derivation details of simplified OFDM transmission equation and resulting signal-to-interference plus noise ratio (SINR) for the case of an insufficient CP. Each…
