  • Spatial channel characterisation of FDD wireless links

    Publication Year: 2001, Page(s):68 - 72
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (360 KB)

    For smart antenna deployments in frequency division duplex (FDD) applications the downlink weight vector can be derived from the uplink steering vector. However, this assumes a degree of correlation between these channels. It is shown here that de-correlation between uplink and downlink power azimuth spectrums (PAS) is significant for frequency offsets as small as 5 MHz in urban environments, with...

    While the first 3G deliveries are soon due to realisation, new ideas about the next generation have emerged the papers and conferences. For example terms systems beyond 3G. The next generation and 4G have been used to define the next step. What does this all mean? Is it fair to speak about the 4G when the previous generation is not even in use yet? Are there some limits for the development? What k... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (348 KB)

    Although, all the users within a cellular network are not stationary, the current cellular network design has as the fundamental assumption exactly this immobility of the users, resulting in treating them as their fixed wireline counterparts. However, cellular networks are quite different primarily because of the phenomenon of handover. This paper builds on the assumption of the Poissonian nature ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (388 KB)

    The CDMA based UMTS transmission technology in which all users simultaneously share the same common range of spectrum gets rather affected by the system interference. The reduction of interference is therefore a key issue in the development of optimal radio transmission in order to increase the system capacity. Power control is a well-known technology to improve the system performance. Different m... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (352 KB)

    It is increasingly the case that users of personal communications systems expect a seamless provision of coverage, whether in rural or urban areas, outdoors or indoors. Existing 2G systems provide a fair degree of indoor coverage from existing micro- or macrocell base stations, though subscribers generally expect to have to co-operate by positioning themselves near windows. Such coverage is increa... View full abstract»

  • Coverage-capacity analysis of opportunity driven multiple access (ODMA) in UTRA TDD

    Cited by:  Papers (21)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (404 KB)

    The multi-hop, ad-hoc wireless networks of ODMA can be shown to reduce overall transmission power compared with single hop transmission, however, for simple receivers and low user density, the actual capacity of UTRA TDD may be marginally reduced from the maximum non-relaying capacity. This paper analyses the capacity of ODMA in relation to the coverage of a cell. It is shown that after the covera... View full abstract»
