    WLANs have adopted radio wave-based technology, for example Bluetooth, IEEE802.11 and the emerging ultra wideband (UWB) systems. The demand for network access is growing rapidly, yet radio bandwidth is limited. In the future, radio frequencies may be insufficient to accommodate a large number of users or devices. As a consequence, infrared indoor wireless communications has been proposed as an alt... View full abstract»

It is a time-varying Dynamic spectrum management (DSM) is one of the key problems in the design of cognitive radio(CR) networks. It is a time-varying and location-dependent optimization problem, equivalent to the well-known graph-colouring problem in graph theory. This problem is known to b... View full abstract»

    New wireless systems expected to provide access to broadband networks are being considered for operation in the unused channels of the VHF and UHF TV bands. These new systems will have to avoid interference to TV broadcast operation and one way to achieve this will be by sensing the presence of broadcast operation in the area and change their operating frequency accordingly. This article deals wit... View full abstract»

    A critical issue in wireless sensor networks isrepresented by the limited availability of energy withinsensor nodes. An effective approach for energy conservationis scheduling sleep intervals for extraneous nodes, while theremaining nodes stay active to provide continuous service.Most previous solutions assumed a perfect radio conditionwith a static, circular coverage. However, in real situations,... View full abstract»

    This paper introduces a collaborative coding algorithm and re-initialized transmission scheme to improve spectral efficiency of two-relay OFDMA networks. By broadcasting the network coded frames through the shared sub-carriers, with specific network coding and frame recovery at each relay node (RN), the proposed algorithm provides 1/3 higher spectral efficiency than the conventional, store-and-for...

    In this paper we propose a soft output detector for theMIMO-CDMA systems with permutation spreading. Insuch systems, the spreading waveforms of each transmitantennas are dependent on the data to be transmitted. Inthe proposed system, information bits are convolutionallyencoded prior to being used in a MIMO-CDMA systemwith permutation spreading. Reliability of the detectedbits in the receiver is ca...

    This paper investigates code synchronization for a recently proposed code-shifted reference (CSR) impulse radio ultra-wideband (IR-UWB) system. In the CSR scheme every symbol with the code-shifted information bits is conveyed by several frames and during each frame only one pulse is transmitted. By assuming that the start of each frame concerning the receiver's clock is known,two code synchronizat... View full abstract»
