Cognitive Radio (CR) is another technology in which a framework can sense its surroundings and adjust to the new working parameters to improve the transmission quality. A flexile and versatile physical (PHY) layer is required to execute the previously stated capacities. In this paper the two spread spectrum procedures to be specific DSSS and FHSS are examined regarding how these meet the PHY la...

Decision support systems (DSSs) are widely used in many organisations (Arslan et al., 2004; Belecheanu et al., 2003; Dey, 2001; Gopalakrishnan et al., 2004; Lau et al., 2001; Puente et al., 2002). However, there is a common tendency to apply experience and techniques gained from large organisations directly to small businesses, without recognising the different decision support needs of the sma...

Precision ranging radios are a critical aid to integrated locating, tracking, navigation, and guidance systems, especially when GPS service is degraded or unavailable [5]. In this work, a high-precision, software-defined, round-trip time-of-flight, direct sequence spread spectrum (DSSS) ranging radio operating in the 2.4 GHz ISM band is presented. This system builds upon our previous brassboard...

The purpose of this study was to determine baseline user satisfaction for 2 computer decision support systems (DSSs) with demonstrated improvement in patient outcome used in a burn intensive care unit. We conducted a survey of staff members of a 16-bed burn intensive care unit (n = 82) using a written, anonymous questionnaire to determine satisfaction for 2 DSSs: a commercial glycemic managemen...

CONTEXT Computer-based diagnostic decision support systems (DSSs) were developed to improve health care quality by providing accurate, useful, and timely diagnostic information to clinicians. However, most studies have emphasized the accuracy of the computer system alone, without placing clinicians in the role of direct users. OBJECTIVE To explore the extent to which consultations with DSSs i...

In a non-cooperative context, receiver has to estimate the communication parameters without any prior knowledge of transmitter, which is highly demanding. Estimating self-synchronous scrambler even more challenging because scrambling sequence affected by input sequence. This paper proposes an improved algorithm for blind estimation using orthogonal property bias condition received signals in di...

To accommodate high-speed data transmissions, it may be necessary to substantially reduce the processing gain of a direct-sequence spread-spectrum (DSSS) system. As a result, intersymbol interference effects may become more severe. In this paper, we present a new structure for maximum-likelihood sequence estimation equalization of DSSS signals on a multipath fading channel that performs the fun...
