FPGA implementation of direct sequence spread spectrum techniques
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This work presents the performance, noise analysis and FPGA implementation of Direct Sequence Spread Spectrum technique. Performance of signal increases as increasing parity bits in Hamming code algorithm. Increasing parity ...
Design of multi-standard RF front end receiver using novel low IF topology
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This thesis presents the multi-standard receiver architecture and the corresponding RF front-end design supporting Bluetooth and IEEE 802.11a WLAN standards. To maximize the level of component share in the proposed ...
Energy efficient data gathering protocol for wireless sensor network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Wireless Sensor Network is made up of hundreds and thousands of miniature electronic devices called node, which have sensors built on them. Functionality of a sensor is entirely application dependent. They can perform a ...
Symbol detection in MIMO systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Multiple input multiple output symbol detection methods are observed under frequency flat fading AWGN channel condition. The modulation method employed is Quadrature amplitude modulation (QAM). The various symbol detection ...
Multi band fractal antenna for satellite application
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Fractal Antenna is the current topic for the research engineering because Fractal Technology allow us to design miniature antennas and integrate multiple band in single device. This antenna is a type of Micro strip antenna ...
Exploring small world effect in ad hoc network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Small world is a highly clustered i.e., a densely and fully connected network, with low degree of separation between the nodes. These networks have inherited the high clustering property of regular networks and low average ...
