SCMA Inspired Sparse Vector Coding: An Enhanced URLLC Transmission Scheme
Zhen-Ming Huang, Zilong Liu, Leila Musavian +1
Sparsity is inherently exploited in sparse code multiple access (SCMA) and sparse vector coding (SVC), yet the interaction between these two has not been explored before. It is int…

Robust SCMA Codebook Design: A Hardware-Aware Autoencoder Approach
Zihao Liu, Zilong Liu, Leila Musavian
Sparse code multiple access (SCMA) is a promising code-domain non-orthogonal multiple access scheme which is transmitted over orthogonal frequency division multiplexing (OFDM) to e…

Non-Orthogonal Affine Frequency Division Multiplexing for Spectrally Efficient High-Mobility Communications
Qin Yi, Zilong Liu, Leila Musavian +1
This paper proposes a novel non-orthogonal affine frequency division multiplexing (nAFDM) waveform for reliable high-mobility communications with enhanced spectral efficiency (SE).…
