Call for Papers: Sparse/Low-rank Tensor Signal Processing for Communication and Radar Systems

To pursue high-quality communication or detection performance, various diversity methodologies have been applied to communication and radar systems, e.g., spatial diversity, temporal diversity, frequency diversity, polarization diversity, etc. Consequently, the transmitted and/or received signals in communication and radar systems always exhibit a multidimensional structure, and can be modeled using tensor algebra tools. In particular, modern communication and radar systems consist of large-scale transmitting/receiving antennas and high speed sampling modules, which leads to a massive volume of data to be processed. On the other hand, the inherent characteristics-of-interesting in the array data are often (or approximately) sparse and low rank. Traditional matrix-based signal processing methods do not fully capture such tensor nature. In comparison, tensor algebra offers fundamental advantages over their matrix counterparts with respect to identifiability and uniqueness. Sparse/low-rank tensor signal processing techniques have been applied in the field of radar and communication systems to mitigate the effect of environmental noise, multi-path propagation, channel inconsistency of receivers and various interferences. These methods can achieve high target detection performance, suppress the background noise and deal with multi-path effect, as well as handle multi-dimensional signals. However, they may also suffer from high computational complexity and model mismatch, etc. Thus, new models and algorithms based on tensor decompositions are needed to improve the performance of communication and radar systems. 

This special issue is intended to solicit high-quality contributions in recent advances for sparse/low-rank tensor signal processing in radar and communication systems. Authors are invited to submit original papers presenting new theoretical and/or application-oriented research including algorithms, models, technology and applications.
