This work conceives dictionary-learning (DL)-based sparse channel estimation schemes for multi-user Terahertz (THz) hybrid MIMO systems incorporating also non-idealities such as hardware impairments and beam-squint effect.Due to the presence of large antenna arrays coupled with frequency selectivity, beam squint effect is significant in THz systems
