AUTO FLIGHT PILOT SIMULATION APPLIED IN REAL TIME AND REMOTE MONITORING USING HIGH SPEED RF DATA LINK FOR UAV / FLIGHT.

ABSTRACT: The use of Unmanned Arial Vehicle (UAV) become vital in the modern world as the activities of UAV is unequal. The main navigation system used in the UAV is a remote controlled pilot system. The real pilot, who is sitting remotely with all control equipment and monitoring system become a real cockpit and it is necessary to control all parameters in real time at higher accuracy.
The project mentioned here is the re ....etc

Abstract
Wireless sensor networks provide the smallest and cheapest form of wireless communicating and computing devices due to the advances in Processor, memory and radio technology. These wireless sensor networks pose significantly different design, implementation, and deployment challenges. In this project, I present a simulation of the wireless sensor network for paging applications. These pagers can provide small data transfer and can be used to transfer small pieces of information between themselves. A pager is a wireless sensor mote wh ....etc

GMSK DEMODULATOR USING COSTAS LOOP FOR SOFTWARE-DEFINED RADIO

ABSTRACT

DSP based implementation of Gaussian Minimum Shift Keying (GMSK) demodulator using Costas loop has been described. The demodulator consists of a Costas loop for carrier recovery, data recovery, and phase detection. For low data rates, ....etc

PLL is a good way to do FM demodulation in analogue domain ,A PLL system can be used to implement an FM demodulator. When a PLL is locked on an FM signal, the VCO tracks the instantaneous frequency of that signal. Since the VCO output tracks the FM signal, and the VCO input voltage is proportional to the VCO output frequency, then the VCO input will be equal to the demodulated signal.

A disadvantage of the PLL technique is that it trickier to get ....etc

Scalable Wireless Ad-Hoc Network Simulation using XTC

Project Pre requisitions:-
The XTC ad-hoc network topology control algorithm shows three main advantages over previously proposed algorithms. First, it is extremely simple. Second, it does not assume the network graph to be a Unit Disk Graph; XTC proves correct also on general weighted network graphs. Third, the algorithm does not require availability of node position information. Instead, XTC operates with a general notion of order over the neighborsâ„¢ page l ....etc

Abstract
A new printed antenna system mounted in an aperture in the roof of a car is evaluated for broadcast signal reception from 88-108 MHz. Results from simulations on the vehicle are compared with measurements. The overall performance of the antenna is also compared to common types of vehicle antennas, the roof monopole and a glass based antenna. Overall the average gain of the antennas was better than -3 dBi for vertical polarization and -10 dBi for horizontal while the input return loss was generally better than -2 dB before matching sec ....etc
