We present correspondence with category Latent Dirichlet Allocation (corr-c-LDA), a novel probabilistic topic model for the task of image and video annotation. The heart of our annotation model lies in introducing the class label information and assuming the dependence relationships between class label and image feature, as well as class label and annotation words. Instead of modeling the image and...
We present a new algorithm for joint timing and channel estimation in OFDM systems with cyclic training symbols. The proposed algorithm employs multiple signal classification (MUSIC) approach for coarse timing estimation and then refines the timing/channel estimation by applying the generalized maximum likelihood rule (GMLR) within a symbol period around the coarse timing for different channel lengths...
This paper proposes a low complex frequency domain channel estimation for ultra-wideband indoor environment. The channel parameters are the attenuations and delays incurred by the signal echoes along the propagation paths. Time-hopping (TH) modulation with binary symbols is assumed. Codewords span a transmission frame. Frames are separated by a guard time to cope with the channel time dispersion....
