Combined state and parameter estimation of dynamical systems plays a crucial role in extracting system response from noisy measurements. A wide variety of methods have been developed to deal with the joint state-parameter estimation of nonlinear dynamical systems. The Extended Kalman Filter method is a popular approach for the joint systemparameter estimation of nonlinear systems. This method c...

In this work performance of Gaussian Minimum Shift Keying (GMSK) modulation is compared with that of conventional QPSK and M-QAM modulation schemes. Use of unfiltered data stream for modulation results in a considerably large bandwidth in the modulated RF signal. Pulse shaping as a signal processing technique has gain grounds as a means to mitigate this problem. Gaussian filter along with squar...

The real time moving object and face detections are used for various security applications. In this paper, we propose FPGA implementation of moving object and face detection with adaptive threshold. The input images are passed through Gaussian filter. The 2D-DWT is applied on Gaussian filter output and considered only LL band for further processing to detect object/face. The modified background...
