    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (452 KB)

    A robust method for asynchronous modulation recognition without a priori knowledge about modulation and transmission parameters is proposed. The generated features are based on modulation dependent spectral lines observed in the estimated spectra of m-th law transformations of the received signal. A twofold robust normalisation scheme is introduced, which is adequate to build significant feature v... View full abstract»

    We propose a MAC protocol for an ad-hoc network architecture, termed the reconfigurable wireless networks, and investigate its network capacity. We discuss the access synchronization and the construction of the network connections features of the MAC protocol. Using event-driven simulation, we evaluate the performance of the scheme demonstrating its behavior for different mobility and traffic para... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (252 KB)

    The phrases communications architecture and C4I architecture are frequently used to describe a variety of capabilities, networks, systems or combinations of them. However, there is little uniformity of understanding in architectural discussions, because the frames of reference are seldom common. This paper uses elements of the International Standards Organization (ISO) functional characteristics o... View full abstract»

    Due to the operation of an IP's addressing and routing algorithms, mobile nodes (such as notebooks, portable workstations and palmtop computers) cannot currently participate while roaming without being reconfigured in tactical wired and wireless networks, strategic networks or the Internet. A node's IP address encodes the network access point to which the node is connected. This prevents IP packet... View full abstract»

    The user capacity of a hypothetical CDMA system, with multiple frequency allocation (FA), is studied in terms of area coverage and sensitivity parameters, under a postulated military scenario in which the system is subject to wideband and partial-band noise jamming. The system is assumed to assign call traffic to different FAs under partial-band jamming, thereby forcing the partial-band jamming to... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (412 KB)

    We present a method to classify various QAM signal constellations by separately analysing the DFT of the phase histogram and applying knowledge about the distribution of the magnitude. The analysis is carried out using the maximum likelihood approach in both cases. In the paper the likelihood functions are derived and a rule to combine these for classification is given. Furthermore the classificat... View full abstract»

    Future military communication networks will have a mixture of backbone terrestrial, satellite and wireless terrestrial networks. The speeds of these networks vary and they are very heterogeneous. As networks become faster, it is not enough to do reactive fault management. Our approach combines proactive and reactive fault management. Proactive fault management is implemented by dynamic and adaptiv... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (752 KB)

    One-half of the life cycle cost of spaced-based intelligence dissemination systems resides in the terrestrial terminals. Of that cost, most is not the price of the terminal but the integration of the terminals into platforms. The future cost of terminals will decrease as COTS (commercial off-the-shelf), GOTS (government off-the-shelf) and NDI (nondevelopmental item) equipment are ushered in, but t... View full abstract»

    The application of the least-mean-square (LMS) and recursive-least-square (RLS) algorithms to the estimation of symbol period is discussed. The algorithms are based on the measurement of the time between two consecutive detected transitions in noisy waveforms. Two versions of the algorithm are developed for white and colored measurement noise models. Conditions are derived that guarantee proper be... View full abstract»

    The novel technique of chip-rate hopping (CRH) has been developed to counter chip-rate detection of direct sequence (DS) spread spectrum communications signals below noise. A laboratory proof-of-concept BPSK DS communications transmitter was designed and implemented. The signal presence was detected with a chip-rate detector examining a number of spectra in order to capture the elusive hops. The b... View full abstract»
