Comparison of Ultra Wide Band Indoor Multipath IEEE 802.15.3 Channel Model
Abstract: ABSTRACT A very large bandwidth of frequency (3.1–10.6 GHz) has been allocated to UWB systems. A single-band UWB signal propagates differently in the lower and upper bands of the spectrum due to the size of its bandwidth. The lower part of the signal can be obstructed more easily and the man-made interferences are not homogeneously distributed over the whole spectrum. The first experimental results obtained for a UWB channel show …

Investigations on PAPR Reduction using PTS Technique for OFDM Communication Systems
Abstract: AbstractOrthogonal Frequency Division Multiplexing (OFDM) is a spectral efficient technique for high data rate communication systems. It also provides robustness to multipath frequency selective fading but suffers from high peak-to-average power ratio (PAPR) and causes high power amplifiers to operate in the nonlinear region. In this paper partial transmit sequence (PTS) as PAPR reduction technique has been investigated. Mathematical modelling and Matlab simulation have been carried out to analyse its …

Nonlinear Channel Equaliser using Discrete Gabor Transform
Abstract: ABSTRACTThe adaptive equaliser makes use of adaptive digital filters whose filter coefficients are modified depending on the channel characteristics at the front end of the receiver. The noise introduced in the channel gets nullified and hence the signal-to-noise ratio of the receiver improves. Discrete Gabor Transform (DGT) helps decorrelate input data because of which the convergence speed of the Mean Square Error (MSE) improves considerably. It is found that the …

Effect of Chronic Inescapable Footshock and Antidepressant Treatment on BDNF/TrkB Levels in Rat Hippocampus
Abstract: Depression is a major health problem globally. Chronic stress arising out of life style or social factors may trigger depression, the molecular basis of which has been attributed to alterations of brain chemicals like neurotrophins. Among these neurotrophins, brain-derived neurotrophic factor regulates many physiological functions in the brain, alteration of which has been well associated with the pathogenesis of depression. Stress-induced helplessness in rodents constitutes a well-defined model to investigate …

A Numerical Model to Study Effect of Potential-Dependent Influx on Calcium Diffusion in Neuron Cells
Abstract: Electrical activity within the brain rapidly encodes information about the world but for these fleeting perceptions to have a lasting impact, long-term changes in the structure and function of neurons must follow. At the synapse, neurotransmitter reception initiates a number of biochemical signaling cascades in the postsynaptic cells, one of the most important of which is the elevation of intracellular calcium. Early events induced by the rise of calcium in …
