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…
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…
Channel Shortening by Large Multiantenna Precoding in OFDM
Renaud-Alexandre Pitaval
A channel delay spread larger than the cyclic prefix (CP) creates inter-carrier/symbol interference (ISI/ICI) in orthogonal frequency-division multiplexing (OFDM). Recent interests…
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…
From Random Matrix Theory to Coding Theory: Volume of a Metric Ball in Unitary Group
Lu Wei, Renaud-Alexandre Pitaval, Jukka Corander +1
Volume estimates of metric balls in manifolds find diverse applications in information and coding theory. In this paper, some new results for the volume of a metric ball in unitary…
