Journal ArticleDOI
Generalized Orthogonal Matching Pursuit
TL;DR: The generalized OMP (gOMP) as discussed by the authors is a generalization of the OMP in the sense that multiple N indices are identified per iteration, and it is shown that the gOMP algorithm can perfectly reconstruct any K-sparse signals (K >; 1) provided that the sensing matrix satisfies the RIP with δNK <; [(√N)/(√K+3√ N)].
Journal ArticleDOI
Ultra-Reliable and Low-Latency Communications in 5G Downlink: Physical Layer Aspects
TL;DR: The physical layer issues and enabling technologies including packet and frame structure, scheduling schemes, and reliability improvement techniques, which have been discussed in the 3GPP Release 15 standardization are elaborate.
Journal ArticleDOI
Compressed Sensing for Wireless Communications: Useful Tips and Tricks
TL;DR: In this article, the authors provide essential knowledge and useful tips and tricks that wireless communication researchers need to know when designing CS-based wireless systems, including basic setup, sparse recovery algorithm, and performance guarantee.
Journal ArticleDOI
