The Rao-Blackwellized particle filter (RBPF) and FastSLAM have two important limitations, which are the derivation of the Jacobian matrices and the linear approximations of nonlinear functions. These can make the filter inconsistent. Another challenge is to reduce the number of particles while maintaining the estimation accuracy. This paper provides a(More)
Rao-Blackwellized particle filter and FastSLAM have become popular tools to solve the simultaneous localization and mapping (SLAM) problem. However, the above techniques have two important potential limitations, which are the derivation of the Jacobian matrices and the linear approximations to the nonlinear functions. Also, one of the major challenges of(More)
This paper addresses the problem of simultaneous localization and map building (SLAM) using a neural network aided extended Kalman filter (NNEKF) algorithm. Since the EKF is based on the white noise assumption, if there are colored noise or systematic bias error in the system, EKF inevitably diverges. The neural network in this algorithm is used to(More)
In this paper, an H-bridge inverter topology with reduced switch count technique is introduced. This technique reduces the number of controlled switches used in conventional multilevel inverter. To establish a single phase system, the proposed multilevel inverter requires one H-bridge and a multi conversion cell. A multi conversion cell consists of three(More)
Traditional fast Discrete Cosine Transforms (DCT)/ Inverse DCT (IDCT) algorithms have focused on reducing the arithmetic complexity. In this manuscript, we implemented a new architecture simultaneous for image compression and encryption technique suitable for real-time applications. Here, contrary to traditional compression algorithms, only special points(More)
This paper proposes and implements an energy efficient, high speed pipelined Multiply and Accumulate (MAC) architecture for DSP applications. A controller has been designed to detect the input pattern such that it bypasses multiplier and accumulator units depending on the consecutive input bits. This architecture is used for both signed and unsigned(More)
The present study focuses on the role of remote sensing and geographic information system (GIS) in assessment of changes in forest cover, between 1931 and 2001, in the Kalrayan hills, Tamil Nadu. The trend of forest cover changes over the time span of 70 years, was precisely analysed using high resolution Satellite data. The study revealed that the forest(More)
Power consumption is the most crucial point of designing any architecture. Till the date so many techniques have been discussed for realizing Digital filters more power efficient. This paper presents a Custom Reconfigurable Power efficient FIR filter which is based on multiplier less configuration using RAG-n algorithm. As multiplier takes the maximum area(More)
