Multi-level Turbo Decoding Assisted Soft Combining Aided Hybrid ARQ [PDF]
, 2010 Hybrid Automatic Repeat reQuest (ARQ) plays an essential role in error control. Combining the incorrectly received packet replicas in hybrid ARQ has been shown to reduce the resultant error probability, while improving the achievable throughput.

Sequential Pre-Coding for MIMO Hybrid ARQ [PDF]
IEEE Communications Letters, 2009 While the conventional codebook is defined only for the initial transmission in the closed-loop MIMO system, this paper proposes a new retransmission structure with a sequence of multiple codebooks, rather than using a single identical codebook for every retransmission.

TAXON, Volume 72, Issue 2, Page 307-359, April 2023., 2023 Abstract Classifications of the pantropical plant family Sapotaceae based solely on morphology have historically recognized between 125 and 53 genera. Phylogenetic analyses using molecular data have repeatedly demonstrated that broad concepts of two large genera belonging to subfamily Chrysophylloideae, Chrysophyllum and Pouteria, are untenable and ...

Progressive Hybrid Precoding and Combining for Massive MIMO ARQ Systems
IEEE Access, 2018 In this paper, we consider a progressive transceiver design for point-to-point massive multiple input multiple output (MIMO) with automatic repeat request (ARQ). As an alternative to address the difficulties such as prohibitive hardware complexity, cost,
