    Spectrum access, efficiency, and reliability have become critical public policy issues. Recent study by FCC Spectrum-Policy Task Force (SPTF) found that while the available spectrum becomes increasingly scarce, the assigned spectrum is significantly underutilized. The term cognitive radio was first defined by Mitola in 1999. Cognitive radio is a novel technology, which improves the spectrum utiliz... View full abstract»

    The Health Information Systems (HIS) literature has pointed to the laggardness of the health sector in embracing strategic (integrated) IS in general or in integrating IS in key clinical areas. Of course, the extent of this laggardness varies from one provider/country to another. The HIS literature pointed to different clinical (e.g., one-on-one practices), organizational (e.g., cost/benefit, poli... View full abstract»

    Summary form only given. Despite their low-complexity and (perceived) efficiency, many traditional wireless communication and networking approaches for handling errors and losses are far from being optimum. For example, popular wireless LANpsilas, such as 802.11 systems, heavily rely on retransmission based schemes for handling corrupted packets. These schemes waste precious wireless bandwidth whe...

    A Mobile Ad hoc Network (MANET) is a transitory, dynamic, decentralised, self-organised and infrastructure-less network. This unique nature introduced new challenges in the security research field such that it became imperative to design new security mechanisms that suit these characteristics. The proposed work contributes to the problem of securing data forwarding in the network layer; this is ac... View full abstract»

    This paper presents a new algorithm for colour digital image watermarking. The 24 bits/pixel RGB images are used and the watermark is placed on the green channel of the RGB image. The green channel is chosen after an analytical investigation process was carried out using some popular measurement metrics. The analysis and embedding processes have been carried out using the discrete cosine transform... View full abstract»

    Information hiding of text in cover images is an effective research area. It simply relies on the fact that the hiding process is kept secret. This paper is concerned with the text in image hiding. The proposed hiding system uses spread spectrum technique together with error correction coding. These are used to increase the security of the system and the reliability of the recovery at the receiver... View full abstract»

  • A rigorous proof of MIMO channel capacity’s increase with antenna number

    Publication Year: 2008, Page(s):49 - 53
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (720 KB) | HTML iconHTML

    It is well known that adding more antennas at the transmitter or at the receiver offers larger channel capacity in the multiple-input multiple-output communication systems. In this paper, a rigorous proof is presented for the fact that the channel capacity increases with an increase in the number of receive antennas and the number of transmit antennas. The proof is based on the famous capacity for... View full abstract»

  • Zero correlation matrix of a MIMO system and its application

    Publication Year: 2008, Page(s):54 - 58

    The correlation between different fading paths in a MIMO system plays an important role in the reduction of MIMO channel capacity. The correlation is caused by the interaction of statistical distribution of incident waves around a receiver and the pattern of receive antennas. We derive a zero correlation condition matrix to the MIMO system based on the received electric signals. To find how to app... View full abstract»
