Channel-Like Fingerprinting Overlays for Authenticating OFDM Signals Using Channel Side Information
We present a method for overlaying orthogonal frequency division multiplexing (OFDM) transmissions with a fingerprint message at the physical-layer, where the fingerprint signal conveys a low capacity communication suitable for authenticating the transmission and further facilitating secure communications. A novel approach is discussed where previous channel-state information (CSI) is incorpora...
متن کاملIndependent Subspace Analysis Using Locally Linear Embedding
While Independent Subspace Analysis provides a means of blindly separating sound sources from a single channel signal, it does have a number of problems. In particular the amount of information required for separation of sources varies with the signal. This is as a result of the variance-based nature of Principal Component Analysis, which is used for dimensional reduction in the Independent Sub...
متن کاملExtrinsic Curvature Embedding Diagrams
Embedding diagrams have been used extensively to visualize the properties of curved space in Relativity. We introduce a new kind of embedding diagram based on the extrinsic curvature (instead of the intrinsic curvature). Such an extrinsic curvature embedding diagram, when used together with the usual kind of intrinsic curvature embedding diagram, carries the information of how a surface is embe...
متن کاملBlind channel equalization using weighted subspace methods
This paper addresses the problems of blind channel estimation and symbol detection with second order statistics methods from the received data. It can be shown that this problem is similar to Direction Of Arrival (DOA) estimation, where many solutions like the MUSIC algorithm or “weighted” techniques (as Deterministic Maximum Likelihood or Weighted Subspace Fitting method) have been developed. ...
متن کاملUsing Informed Coding and Informed Embedding to Design Robust Fingerprinting Embedding Systems
Several new video and image watermarking proposals are based on Informed Coding and Informed Embedding. However, these systems can be not easily used in fingerprinting schemes because they do not satisfy the marking assumption defined in [1]. In this paper we discuss some guidelines to adapt a watermarking system based on informed coding and informed embedding to a generic fingerprinting code, ...
