Vehicular Channel Characterization in Orthogonal Time-Frequency Space
Original language description
Orthogonal time-frequency space (OTFS) modulation has been suggested as modulation scheme for the fifth generation of wireless communications and beyond. The scheme is promoted as especially well apt to tackle future challenges of high mobility, millimeter wave communications (mmWave) and massive Multiple-Input Multiple-Output (MIMO). In this paper we investigate the observed channel properties in the OTFS domain from mmWave vehicular crossroads measurements. To assess the sparsity of the resulting delay-Doppler channel, we use Akaike's information criteria, which consider the trade-off between mean squared error and overfitting. Our analysis shows that in the OTFS domain, the observed channel is in deed sparse, with an optimal number of 16 channel taps out of up to 1344 possible. Our analysis furthermore shows that this property of observing sparse channels is caused mainly by the high number of orthogonal symbols resulting from modulation in two domains.
