Due to high penetration losses, millimeter wave channels are formed of few paths. Most channel estimation procedures exploit this property by sounding the channel in multiple directions and then identifying those yielding the largest power. Whether in initial access or tracking mode, the beams for sweeping the channel have maximum gain towards a small range of angles. These beams are heuristic in nature and may not lead the best estimation/tracking performance. In this paper, we investigate… CONTINUE READING
