Channel state information derived from channel estimation is important for receivers to accurately recover the transmitted data. In this paper Channel estimation in OFDM in frequency domain for slow fading channel is considered. The new channel covariance matrix is defined & computational complexity is shown to be reduced. The results of the research(More)
A different and efficient method of image hiding is proposed here. It is based on unitary similarity transformation, involving calculation of eigen values and eigen vectors of a matrix and then transforming it into a diagonal matrix. Only secret image needs to be transformed and is then embedded to the cover image. Inverse transformation can be used to(More)

Wind energy is one of the promising and fast growing green energy resources. It helps in mitigating the global environmental issues. With the increasing share of wind energy it is also important to improve the performance of the wind generators at variable wind speed and load changes. The present paper analyzes the effect of pitch control on the torque,(More)
Active noise control accuracy depends on how much destructive interference exists between the primary noise and the noise (anti noise) generated by secondary source. In this paper firstly multilayer perceptron (MLP) neural network is designed and trained with extracted features of noise signals for classification and then Empirical Mode Decomposition (EMD)(More)
