1. Utilizing Neural Networks To Adaptively Demodulate And Decode Signals In An Impulsive Environment
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för datalogiSammanfattning : Electromagnetic disturbance can be detrimental to the performance of a radio communication system, and in today’s society where more and more electronic devices are present in our everyday life it is increasingly vital to consider man-made interference. A communication system can take into consideration the noise characteristics and by doing so will excel in such areas, however, this follows that the algorithms utilized in such systems are more computationally complex and are therefore slow.

2. Study of industrial environment using Zigbee protocol and modeling industrial noise
Kandidat-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskapSammanfattning : This thesis is focused on the industrial environment. This study aims to understand the difficulties wireless communications have when performing in these types of environment with a specific standard (and protocol) Zigbee. LÄS MER
3. Symmetric alpha-Stable Adapted Demodulation and Parameter Estimation
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Signaler och systemSammanfattning : Transmission and reception of signals in wireless communication systems is affected by additive interference corrupting the signal. Traditionally, the interference is assumed to be AWGN and the system designs are usually based on that assumption. LÄS MER
4. Suppression of impulsive noise in wireless communication
Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskapSammanfattning : This report intends to verify the possibility that the FastICA algorithm could be applied to the GPS system to eliminate the impulsive noise from the receiver end. As the impulsive noise is so unpredictable in its pattern and of great energy level to swallow the signal we need, traditional signal selection methods exhibit no much use in dealing with this problem.

5. QAM and PSK Modulation Schemes under Impulsive Noise
Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskapSammanfattning : Nowadays most of the communications systems are designed considering only to work under AWGN (Additive White Gaussian Noise). But the implementation of wireless systems in industrial facilities brings different kind of interference from machines or any other kind of electronic devices. LÄS MER
