Abstract
Orthogonal Time Frequency Space (OTFS) modulation has recently been proposed for communication in doubly selective channels. Together with millimeter waves, OTFS seems to be one of the promising candidates for beyond-5G communication systems. In this paper we present the performance of an OTFS system with an Linear Minimum Mean Square Error (LMMSE) equalizer in the presence of main hardware impairments extracted from our millimeter-wave setup in the 60 GHz band.
