In this paper, the performance of cooperative spectrum sensing (CSS) is assessed in the presence of Hoyt fading. A cognitive radio (CR) user, which senses the primary users (PUs) using an energy detector (ED) in sensing channel (S-channel), is censored on the basis of the quality of the reporting channel (R-channel). A threshold-based censoring scheme is used: CR users, whose estimated R-channel fading...
In this paper, the performance of a cooperative spectrum sensing (CSS) is evaluated, considering maximal ratio combining (MRC) fusion in the presence of Rayleigh fading. A cognitive radio (CR) senses the primary users (PUs) using an energy detector (ED) in the sensing channel (S-channel). If a CR is selected to transmit its local decisions to a fusion centre (FC), it does so using a reporting (R)-channel...
Simulation of the spectrum sensing towards the development of cognitive short range radar (CSRR) is presented in this paper. Also, the classification of the moving objects, another important issue in ITS, is addressed here. A convenient way of object classification is on the basis of 2D radar imaging. As a first step, in this work an ISAR image formation is explained and simulated. Only Fourier transform...
Intelligent transport system (ITS) deals with the remote sensing as well as access to the Internet and multimedia on the move. There is a need for a system that supports both remote sensing and communication aspects with simple and reconfigurable hardware. In the present work MATLAB/SIMULINK based modeling of such a system is done based on DSSS. Hardware realization of this model is achieved through...
This paper addresses the issue of the correction of registration errors due to the presence of biases in the measurements when multiple sensors are used for tracking targets. The problem is formulated as one of recursively estimating biases, and is addressed by an application of the technique, using an augmented Kalman filter, of simultaneously estimating the sensor biases and the state vector (of...
