    In this paper we study the problem of finding the input load that optimizes the total throughput in circuit switched, multihop, wireless networks that are subject to QoS constraints on blocking probability. By doing so we are able to “size” the network capability for a given admission-control policy, thereby determining how much traffic the network can support as well as the offered lo...

    We describe a novel modular learning strategy for the detection of a target signal of interest in a nonstationary environment, which is motivated by the information preservation rule. The strategy makes no assumptions on the environment. It incorporates three functional blocks: (1) time-frequency analysis, (2) feature extraction, (3) pattern classification, the delineations of which are guided by ... View full abstract»

    We previously presented a novel multichannel linear equalization scheme for a TDMA based cellular/PCS communication system commensurate with the US IS-136 standard. This scheme assumes at least two different channels with oversampling at each channel. For a given channel, it was shown that the frequency response of the associated RF multipath channel may be well approximated over the raised cosine... View full abstract»

    The usability of tactical radio systems is strongly affected by the characteristic of the VHF mobile radio channel. The design of a channel sounder and preliminary measurements are presented. The channel sounder uses a chirp impulse compression technique based on a surface acoustic wave (SAW) filter with a bandwidth of 6 MHz in the receiver. The transmitted chirp is generated digitally and is desi... View full abstract»

    The serial search DS code acquisition in a nonselective time-variant channel is analyzed. The stationary random signal amplitude is supposed to be constant during each single/multiple dwell test interval and independent of that on any other test interval. The dependence of the mean acquisition time on the random amplitude is eliminated by averaging over the given amplitude distribution. As an exam... View full abstract»

    We propose a novel signal-selective approach to enumerating the signals of interest (SOIs) impinging upon an array of antennas. This new signal selective information theoretic criterion (SSITC) is derived by formulating the likelihood function for parameters of second-order cyclostationary signals in unknown stationary interference plus noise, and then applying Rissanen's MDL principle. We demonst... View full abstract»

    Today's internetwork technology has been extremely successful in linking huge numbers of computers and users. However, to date, this technology has been oriented to computer interconnection in relatively stable operational environments, and thus cannot adequately support many of the emerging civilian and military uses that require a more adaptive and more easily deployed technology. In particular,... View full abstract»
