Low-Complexity Equalization for Orthogonal Time and Frequency Signaling (OTFS)
Thomas Zemen, Markus Hofer, David Loeschenbrand
Recently, a new precoding technique called orthogonal time-frequency signaling (OTFS) has been proposed for time- and frequency-selective communication channels. OTFS precodes a da…
Iterative Detection for Orthogonal Precoding in Doubly Selective Channels
Thomas Zemen, Markus Hofer, David Loeschenbrand +1
Ultra-reliable wireless communication links require the utilization of all diversity sources of a wireless communication channel. Hadani et al. propose a two dimensional discrete s…
A time-variant channel prediction and feedback framework for interference alignment
Zhinan Xu, Markus Hofer, Thomas Zemen
In interference channels, channel state information (CSI) can be exploited to reduce the interference signal dimensions and thus achieve the optimal capacity scaling, i.e. degrees…
