    Summary form only given. Distributed source coding has emerged as an enabling technology for sensor networks. It refers to the compression of correlated signals captured by different sensors which do not communicate between themselves. Distributed source coding finds its foundation in the seminal work of Slepian-Wolf (1973) and Wyner-Ziv (1976). The proof of the Slepian-Wolf W theorem is based on ... View full abstract»

    The original JPEG (Joint Photographic Experts Group) still image data compression standard (ITU-T T.81 - ISO 10918:1 ) was frozen in the early 90psilas. It had several parts, but most users are only aware of the Baseline mode. This widely used standard was the effort of a joint committee sponsored by ISO/IEC and ITU-T (formerly CCITT). The original committee JPEG committee moved on and created sev... View full abstract»

    Summary form only given. Multimedia coding technology, after about 20 years of active research, has delivered a rich variety of different and complex coding algorithms. Selecting an appropriate subset of these algorithms would, in principle, enable a codec designer to produce any desired trade-off between compression performance and implementation complexity. Currently, interoperability demands th... View full abstract»

    It is well known that both gain and noise figure depend on the source impedance. Minimum noise figure and maximum gain are two goals that cannot be reached simultaneously. In our particular case the problem consists of the fact that the source is a radiating element, e.g. a bow-tie radiator. All influences in the near field of this element cause a change to the source impedance. Thus, we have to a... View full abstract»

    Cell overloading is a bandwidth efficient scheme to increase the number of users in a fixed bandwidth for mobile applications. One of the efficient schemes to overload a CDMA system is to use two sets of orthogonal signal waveforms (O/O) [2]. An iterative soft decision interference cancellation receiver (SDIC) scheme is used to cancel interference between the two sets of users. In this paper, the ... View full abstract»

    Overloading is a technique to accommodate more users than the spreading factor N. This is a bandwidth efficient scheme to increase the number of users in a fixed bandwidth for mobile communication. One of the efficient schemes to overload a CDMA system is to use two sets of orthogonal signal waveforms (O/O). The first set is assigned to the N users and the second set is assigned to the additional ... View full abstract»

    An iterative least squares (LS) based channel estimation method for superimposed training (ST) based OFDM systems is proposed. The performance of the method is analyzed in terms of the mean squared estimation error (MSEE) and its impact on the bit error rate (BER) of the OFDM system is studied. A training sequence selection criterion that jointly optimizes the MSEE and the BER of the OFDM system a... View full abstract»

    In order to evaluate digital color images and videos, many objective metrics have been developed over the years. Some of these metrics correlate well with the subjective perception of distortions caused by a given digital processing on such color images or videos. This work presents a comparison between subjective assessment and objective metric based on SCIELAB color space. Color image samples as... View full abstract»
