Bit Error Performance of Orthogonal Space-Time Block Codes over Time-Selective Channel
— Most of the existing works on space-time block codes (STBC) assume the channels are quasi-static, i.e., they remain invariant within one block. This assumption is not always tr...

Shape-Based Retrieval of Articulated 3D Models Using Spectral Embedding
Abstract. We present an approach for robust shape retrieval from databases containing articulated 3D shapes. We represent each shape by the eigenvectors of an appropriately define...
