Abstract: This paper investigates the downlink channel estimation problem for frequency division duplex (FDD) multi-user massive multiple-input multiple-output (MIMO) systems. We model this problem ...

MONTPELIER – Gov. Phil Scott has hailed the awarding of funding in Vermont for a rural health program that was included in the federal One Big Beautiful Bill Act, signed into law in July. “Today, the ...

Abstract: We propose a novel method for performing channel estimation (CE) for an orthogonal time frequency space (OTFS) modulated waveform that exploits the recently introduced pilot structure with a ...
