    In this talk, an overview of enormous potential of improving spectral utilization by using cognitive radio is presented. The current main focus on cognitive radio design is to research and develop adaptive radio access technologies, that have lead to many challenges in physical layer, medium access control (MAC) layer and cross layer design. Moreover in the talk, research scopes and challenges tha... View full abstract»

  • A Game-Theoretic Approach to Energy-Efficient Modulation in CDMA Networks with Delay Constraints

    A game-theoretic framework is used to study the effect of constellation size on the energy efficiency of wireless networks for M-QAM modulation. A non-cooperative game is proposed in which each user seeks to choose its transmit power (and possibly transmit symbol rate) as well as the constellation size in order to maximize its own utility while satisfying its delay quality-of-service (QoS) constra...

    In this paper, genetic algorithm (GA) was applied to orthogonal variable spreading factor (OVSF) code tree reassignment problem with adaptive population size, which is constructed according to existing OVSF code tree density. In order to improve the ability of GA, we employ so-called "dominance & diploidy" structure to adapt to changing traffic conditions. Simulation results show that the GA p... View full abstract»

    An integrated artificial intelligence optimised cellular radio channel allocation and call dropping algorithm is presented. The components of the system comprise a new genetic algorithm (GA) based channel allocation scheme, and a novel application of fuzzy logic to call dropping technique. The new method is compared to both random allocation and to a conventional allocation approach. The results s... View full abstract»

    Fixed and mobile communications convergence scenario under the user perspective is being depicted as combination of wireless and cellular networks. This is possible by the use of multimode terminals, and application servers located in the core network, that facilitates the handover between the different base stations whatever the wireless or cellular standard is used in the convergent network. Sin... View full abstract»

    Ensuring reliable and efficient packet transmission in the error prone shared radio channel is one of the ways to support QoS for integrated services in IEEE 802.16 wireless MAN network. To minimize the wasted bandwidth in transmitting corrupted packets, it is critical for the subscriber station and base station to know the channel state at and schedule the next transmission. A periodical handshak... View full abstract»

  • Active Inductor-Based Oscillator: A Promising Candidate for Low-Cost Low-Power Multi-Standard Signal Generation

    This paper presents design techniques to enhance the tuning range and improve the phase noise performance of tunable active-inductor (TAI) oscillators. Noise analysis of the TAI suggests a direct trade-off between the range of tunable inductance and the output noise. Reducing the effective feedback resistance reduces the phase noise of the VCO, but simultaneously reduces the inductive tuning range... View full abstract»
