An analytical approach is developed to derive the expression of the Multiple Access Interference (MAI) and Bit Error Rate (BER) of a MC-DS-CDMA system using multiple receiving antennas with Maximal Ratio Combining (MRC), considering Rayleigh fading channel. The analysis is extended to RAKE receiver with Equal Gain Combining (EGC). The results are presented(More)
Glioma is a type of brain tumor, originates from glial cells. Approximately 80% of them are malignant. Based on pathological evolution of tumor, they can be classified into two types of tumor - high grade & low grade glioma. In this paper, the segmented area obtained from the conventional region-growing approach is automatically selected as the the(More)
The present work envisages mathematical modeling of induced focal cerebral ischemia in animal model using EEG data with the help of Fast Fourier Transformation method. Amongst several analysis methods, spectral analysis methods are important because it detects the frequencies and characteristics changes of brain waveforms depending on the brain function(More)
Recently the development of brain-computer interface applications has drawn the attention of research community as it can assist physically challenged people to communicate with their brain electroencephalogram (EEG) signal. In this paper, a Brain-Computer Interface (BCI) is designed using electroencephalogram (EEG) signals where the subjects have to think(More)
This paper proposes an efficient and effective method to classify motor tasks from ECoG signals in session-to-session transfer. Real time BCI systems require the classification algorithm to be able to overcome the difficulties due to session-to-session transfer. The feature vector proposed here consists of the higher order statistical properties of the(More)
Recently the development of brain-computer interface applications has drawn the attention of researchers as it can assist physically challenged people to communicate with their brain electroencephalogram signal. In this paper, a Brain-Computer Interface (BCI) is designed using EEG signals to differentiate between two mental arithmetic tasks performed by the(More)
The aim is to design a low cost, multi-use, user-friendly and durable hearing aid. Hearing aid is a kind of device which facilitates hearing for hearing impaired person. In addition to have good quality, to keep the low cost was one of the major challenges. So, the plan was to design a hearing aid which will be cost effective and should have good additional(More)
