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…
Set Size Bound for Aperiodic Z-Complementary Sets
Cheng-Yu Pai, Yu-Che Tung, Zhen-Ming Huang +1
The widely and commonly adopted upper bound on the set size of aperiodic Z-complementary sets (ZCSs) in the literature has been a conjecture. In this letter, we provide detailed de…
Sparse Zero Correlation Zone Arrays for Training Design in Spatial Modulation Systems
Cheng-Yu Pai, Zilong Liu, Chao-Yu Chen
This paper presents a novel training matrix design for spatial modulation (SM) systems, by introducing a new class of two-dimensional (2D) arrays called sparse zero correlation zon…
Enhanced Cross Z-Complementary Set and Its Application in Generalized Spatial Modulation
Zhen-Ming Huang, Cheng-Yu Pai, Zilong Liu +1
Generalized spatial modulation (GSM) is a novel multiple-antenna technique offering flexibility among spectral efficiency, energy efficiency, and the cost of RF chains. In this pap…
Sparse Complementary Pairs with Additional Aperiodic ZCZ Property
Cheng-Yu Pai, Zilong Liu, Chunlei Li +1
This paper presents a novel class of complex-valued sparse complementary pairs (SCPs), each consisting of a number of zero values and with additional zero-correlation zone (ZCZ) pr…
Two-Dimensional Golay Complementary Array Sets from Generalized Boolean Functions
Cheng-Yu Pai, Chao-Yu Chen
The one-dimensional (1-D) Golay complementary set (GCS) has many well-known properties and has been widely employed in engineering. The concept of 1-D GCS can be extended to the tw…
