    In this paper, the design and measurement of a low cost high performance SPLT gallium-arsenide switch are discussed. The design uses a novel approach to reduce receive path loss and to achieve >40dB TX-RX isolation. It is implemented with the Filtronic Compound Semiconductors 0.5um D-mode GaAs pHEMT process. The switch can be configured to connect different GSM / GPRS / EDGE 850 / 900 / 1800 / 190... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (284 KB) | HTML iconHTML

    In this paper we consider the use of MCCDMA (Multi-Carrier Code Division Multiple Access) schemes with a frequency-domain orthogonal spreading. The transmitter structure is especially modified for reducing the envelope fluctuations of the transmitted signals. An analytical approach for the performance evaluation is also included which relies on the Gaussian characteristics of MC signals with a hig... View full abstract»

    Multi-carrier CDMA (MC-CDMA) is one of the promising wideband transmission techniques for the fourth generation mobile communication. This paper studies the possibility to improve its performance in the downlink Rayleigh channel by proposing an Adaptive Code Length (ACL) scheme. One of the main reasons for performance degradation is the interference due to the fadingnature of the mobile channel. T... View full abstract»

    This paper explores the feasible limits for complexity reduction of a very simple front-end block for the calculus of phase transition metrics on a continuous phase modulation (CPM) receiver. A quasi-optimum receiver of very low complexity is attained by splitting the function of the optimum receiver bank filters in two blocks: calculus of projections coefficients on a low dimensional space of Wal...

  • The M-algorithm on the detection of CPM schemes on the minimum euclidian distance upper bound

    The impact of the M-algorithm on continuous phase modulation (CPM) detection is analyzed when replacing the common Viterbi algorithm (VA) on the maximum likelihood sequence detection (MLSD) block. The algorithm is presented as a reduced complexity sequence detection algorithm in which not all transitions are propagated, being only retained a small subset of paths. A rule is found concerning the lo... View full abstract»

    A distributed antenna diversity system can he effective in combating the effects of shadowing, but this results in some antenna units being closer to adjacent cells. Studying this in a free space propagation environment we show that a distributed antenna has marginally worse iutercell interference than a single antenna at the centre of a cell when the total transmission power in the two systems ar...

  • Novel block error rate model for rayleigh and sub-rayleigh fading channels

    Publication Year: 2004, Page(s):45 - 48
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (276 KB) | HTML iconHTML

    A novel method to estimate block error rates (BLER) in the Rayleigh and sub-Rayleigh fading channels is proposed. The suggested model is based on a finite state Markov chain. The proposed model is usable over a wide range of fading rates and is analytically tractable. The general analytical results are specialized to the case of differential phase shift keying (DPSK) and to the case of Jakes?? fad... View full abstract»

    A novel vector channel simulator for sub- Rayleigh correlated fading is presented. The fading process is described as the product of a complex Gaussian and an exponentially correlated process produced by a noise-driven non-linear system. An isotropic scattering environment is assumed. The proposed model is studied using the example of Nakagami fading with m View full abstract»
