DOI: 10.1109/lcomm.2017.2701801
Abstract: Multicarrier-low-density spreading multiple access (MC-LDSMA) is a novel non-orthogonal multiple access scheme, which exploits a multidimensional codebook based on the sparse spreading technique. In this letter, instead of assuming the ideal Gaussian inputs, we contribute… read more here.

DOI: 10.1109/tcomm.2020.3035233
Abstract: With practical finite alphabet inputs, usually the throughput of a practical communication system cannot reach the capacity based on assumption of Gaussian inputs. In this paper, we study the resource allocation strategy for multiple-input multiple-output… read more here.
