High mobility broadband communication channels tend to suffer from multipath fading with large Doppler spread, i.e. fast time-varying multipath fading.  Such doubly selective fading becomes more severe when the carrier frequency bands move higher to mm-wave or THz bands.  To build a communication receiver which is able to track the fast time variation of the channel states without requiring excessive pilot overheads, and to handle the severe inter-symbol interference or inter-carrier interference (depending on whether single-carrier or multi-carrier signalling is employed), is a major engineering challenge.  I will share recent results in advancing this research by exploiting basis expansion model (BEM) channel estimation, pseudo-pilot, joint channel estimation and equalization, and other concepts.  Once the detrimental effects of doubly selective fading are mitigated, the receiver will be able to benefit from the enhanced time/frequency diversity in the channel.
