Simplified universal soft demapper for gray-mapped constellation
2015 International Wireless Communications and Mobile Computing Conference (IWCMC), 2015Bit-interleaved coded modulation (BICM) systems with high order constellations and signal space diversity (SSD) are deployed in DVB-T2 and recommended for potential use in 3GPP-LTE standards for its high spectral efficiency and diversity gain. However, in such systems, previous soft demapping algorithms show either extremely high computational ...

Sequences with good correlation property using Gray mapping
IEEE Information Theory Workshop 2010 (ITW 2010), 2010This paper provides two construction methods of sequence using the Gray mapping. In the first method, a quaternary sequence with R max = 2 for N ≡ 2 (mod 4) which is the same as the best known Rmax, is proposed. The sequence is constructed by the Gray mapping of a binary sequence with even period and its half-period shift.

QTL mapping of resistance to gray leaf spot in maize
Theoretical and Applied Genetics, 2012Gray leaf spot (GLS), caused by the causal fungal pathogen Cercospora zeae-maydis, is one of the most serious foliar diseases of maize worldwide. In the current study, a highly resistant inbred line Y32 and a susceptible line Q11 were used to produce segregating populations for both genetic analysis and QTL mapping. The broad-sense heritability (H (2))

QTL mapping of resistance to gray leaf spot in ryegrass
Theoretical and Applied Genetics, 2005Gray leaf spot (GLS) is a serious fungal disease caused by Magnaporthe grisea, recently reported on perennial ryegrass (Lolium perenne L.), an important turf grass and forage species. This fungus also causes rice blast and many other grass diseases. Rice blast is usually controlled by host resistance, but durability of resistance is a problem.
