- W2188038773 abstract "Allexisting training signal designs forchannel esti- mation inOFDM systems neglect phasenoise orbothfrequency offsets andphasenoise. Inpractice, frequency offset andphase noise areunavoidable andcanseriously degrade theperformance ofOFDM systems. Inthispaper, we address theproblemof designing optimal training signals fortheestimation offrequency- selective channels inMIMO OFDM systems withfrequency offset andphasenoise. Analytical andsimulation results for thecorresponding channel estimation meansquareerrorare presented. Channel estimation performance ismoresensitive to frequency offset andphasenoise inMIMO thaninSISOOFDM systems. Theperformance improvement achieved bytheproposed training signals becomesmoresignificant formoderate-to-high values ofSNR,frequency offset, andphasenoise level." @default.
