  • Daniels, Graham.; Suzuki, Hajime.; Hedley, Mark. (2007-03-12)
    Abstract—This paper examines mode adaptation for MIMOOFDM-BICM systems. Our results are based on measured MIMO-OFDM channels in an indoor environment at 5 GHz. We demonstrate that a simple zero-forcing spatial multiplexing ...
  • Holland, I. D; Cowley, W. G; and Burnet, C. (2007-03-12)
    We consider issues related to the design of a 60GHz short-range wireless local area network (WLAN) using low cost components and aiming at data rates on the order of 1Gbit/s. It is anticipated that the use of adaptive ...
  • Manteuffel, Dirk (2007-03-12)
    The design of UWB systems for consumer electronic application requires the integration of the antenna for aesthetical design reason. This paper discusses the influence of the integration on the performance of UWB antennas ...
  • Al-Obaisat, Yazeed; Braun, Robin (2007-03-12)
    With the recent technological advances in wireless communications, integrated digital circuits, and micro electro mechanical systems (MEMS); development of wireless sensor networks has been enabled and become dramatically ...
  • Pawlikowski, Krzysztof.; Perera, Shehan.; Sirisena, Harsha. (2007-03-12)
    An analysis of the impact of the packetization interval for constant bit rate traffic has been done in the context of IEEE 802.16 MAC layer. Bandwidth used for overheads which include lower layer headers as well as ...
  • Azim, Mohammad Abdul; Jamalipour, Abbas (2007-03-12)
    For the flat wireless sensor networks, we investigate the optimization problem of the routing path based on the metrics: distance, power and link usage to maximize the lifetime of the sensor networks. We employ the well ...
  • Flores-Centurion, Bruno (2007-03-12)
    The close relationship between the peak factor of a QPSK/OFDM system and the one from a 16-QAM/OFDM system is presented and analyzed. It is shown that a 16-QAM/OFDM system shows larger peaks and is more difficult to analyze ...
  • Simic, Ljiljana.; Berber, Stevan M. (2007-03-12)
    This paper presents the implementation of a multi-user chaos-based communication system in DSP. The system is based on the chaotic phase shift keying (CPSK) digital modulation scheme, where chaotic signals are used as the ...
  • Kubik, Kurt.; Einicke, Garry.; Zhang, HuiYao.; Homer, John. (2007-03-12)
    Currently, voice traffic (both local and long-distance) is gradually moving from traditional circuit-switched networks to IP-based, packet-switched networks. Another dominant trend is the development of mobile ad hoc ...
  • Claesson, Ingvar.; Mohammed, Abbas.; Khan, Muhammad Gufran.; Nordberg, J¨orgen (2007-03-12)
    The industrial environments are an important scenario for ultra wideband (UWB) communication systems. However, due to large number of metallic scatterers in the surroundings, the multipath offered by UWB channels is dense ...
  • Homer, John.; Gujrathi,Mandar.; Cendrillon, Raphael. (2007-03-12)
    Crosstalk in DSL leads to significant performance degradation and large losses in data-rate. Several crosstalk cancellation techniques have been proposed to address this problem, however, in the existing literature the ...
  • Huangy, MengWei.; Dong, LiJun.; Kikuchi, Hisakazu.; Zhou Jie. (2007-03-12)
    Spatial correlation is one of the impairment practical Multiple-Input Multiple-Output (MIMO) wireless communication systems have to be coped with. Capacity increases promised by MIMO systems mostly depend on the spatial ...
  • Soudani, Nabila.; Bouallegue, Ridha. (2007-03-12)
    Multicarrier (MC) systems, such as OFDMA (Orthogonal Frequency Division Multiple Access), which are quite developed in the literature, were shown to be the adequate solution for multipath transmission. However, even with ...
  • Kogeda, Okuthe P.; Agbinya, Johnson I. (2007-03-12)
    Cellular network service providers compete with each other for the vast and dynamic market that is characterized by the ever-changing services on offer and technology. These services require very reliable net-works that ...
  • Scanlon, W. G.; Ziri-Castro, K. I.; Evans, N. E. (2007-03-12)
    Human occupants within indoor environments are not always stationary and their movement will lead to temporal channel variations that strongly affect the quality of indoor wireless communication systems. This paper describes ...
  • Wilson, Carol (2007-03-12)
    With the growth of wireless technology for an ever-increasing range of devices, services, applications and users, the role of spectrum management is becoming more complex and difficult. National and international spectrum ...
  • Kerans, A. J.; Squires, C. D.; Lensson, E. S. (2007-03-12)
    This paper describes three methods of calculating required interference protection ratios for Fixed Link radiocommunications receivers, using ITU-R prediction methods. The Initial Planning Method in common use in Australia ...
