A multiple description method for wavelet based image coding
We propose a new multiple description method for wavelet transform coded images. The partitioning of the coefficients at the encoder is combined with concealment at the decoder to...

Tomlinson-Harashima Precoding for Broadcast Channels with Uncertainty
— We consider the design of Tomlinson-Harashima (TH) precoders for broadcast channels in the presence of channel uncertainty. For systems in which uplink-downlink reciprocity is ...

Reliable adaptive modulation and interference mitigation for mobile radio slow frequency hopping channels
: Due to correlated fading in frequency hopping (FH) wireless communication systems, it is possible to predict the future channel state information (CSI) for one frequency based on...

Grassmannian beamforming for MIMO amplify-and-forward relaying
Abstract— In this paper, we consider the beamforming codebook design problem for the half-duplex MIMO amplify-andforward relay channel with Rayleigh fading. The analysis is divid...
