This system process data using DSP processor and transmits processed data using wireless RF module CM2025 which has the programmable carrier frequency in the range 2.3 GHz to 2.5 GHz. Data and audio signals are digitally modulated and transmitted over the wireless medium using wireless RF module. Binary Phase Shift Keying (BPSK) technique or Direct Sequence Spread Spectrum (DS/SS-BPSK) technique is used for the modulation purpose.

While performing experiment microstrip antennas were preferred with transmission line model, cavity model and partly full wave model (which includes the primarily integral equations/moment method). Out of three transmission line model is the simplest and more important it possesses the good physical strength but it has a disadvantage of less accuracy. When compared to transmission line model cavity model is more accurate but its physical design is complex in nature. Best suited model will be full wave models they are extremely accurate versatile and can treat single elements, finite and infinite arrays, stack https://journalnx.com/journal-article/20150110

The main design goal is to transform S- domain Analog PLL to the Z-domain of DPLL without redesigning model. Additionally, this paper present design, analysis, mathematical modelling, mathematical analysis of algorithms which are Impulse-Invariance Algorithm (IIA), Zero-Order Hold Algorithm (ZOHA), Bilinear Transform Algorithm (BLTA) and Matched Pole-Zero Algorithm (MPZA). Design of DPLL which is based on all discretization algorithms are presented and simulated using MATLAB 13a and Xilinx ISE 14.7 system generator. We present the comparative analysis of simulation from which it is found that BLTA is the most celebrated algorithm. Moreover, The BLTA based structure of DPLL adapts the response to allow the DPLL to lock faster than other discretized DPLL. Analysis and steps of the discretization algorithms is discussed and results of MATLAB an...

In this paper, we studied the technological revolution that is SDR communication system consists of an antenna contained with the RTL SDR USB dongle RTLU3832 and freeware GNU radio software support which highly reduce the limitations of the controlled radio. The SDR device are widely used to examine the radio Spectrum and digitize I/Q signals that are being transmitted in the range 25 MHz to 1.75 GHz by the digital communications community. The frequency bands that contains signals such as FM radio, ISM signals, GSM, 3G and LTE mobile radio, GPS, and so on can be sampled in this wide operating range. SDR give us wide scope to hold the experimentations on the real world signals with cost efficient hardware solution and GNU radio flowgraph. FM reception with SDR model is studied ...

In order to overcome this challenge, we have designed an epilepsy alert system, which takes the raw EEG signal, to monitor the blood pressure and the accelerometer application for human fall detection. The raw EEG signal is captured using a Brain Computer Interface module. This design is done using MATLAB GUI. The EEG raw signal is trained by using neural networks and a total of 500 epilepsy patient data is fed to train the network. Accuracy varies with different number of epochs. As the number of epochs increases, the accuracy will also be increased. Fuzzy system is designed to detect the epilepsy with three main parameters.
