4. 13. A Diagnostic Tool for the Causes of Packet Corruption in Wireless Sensor Networks

   University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

   Author : Wenxuan Jiang; [2015]
   Keywords : Wireless Sensor Network; Packets Corruption; RSSI; Logistic Regression;

   Abstract : The two main causes of packet corruption in wireless sensor network are multipath fading and WiFi interference. Identifying the cause of the corruption can be used to improve the reliability of the transmission. If the corruption is caused by WiFi interference, the network could change the channel to a free one. READ MORE

5. 14. A Study Of Multipath Wave Propagation Using Nero2d and FFT

   University essay from Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM

   Keywords : FFT; Radio channel; Impulse response; Fast multipole method;

   Abstract : In this report, the Fast Fourier Transform is described briefly. An implementation, inthe form of the Fortran code four1, is tested to verify the accuracy. A two-ray modelfor wave propagation above a flat earth is discussed. The case with AM modulation isimplemented in a Mathematica script. READ MORE

6. 15. Performance Evaluation of Error Correcting Techniques for OFDM Systems

   University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

   Author : Yasir Javed Qazi; Jawad Ahmed Malik; Safwan Muhammad; [2014]
   Keywords : OFDM; Linear block codes; Convolution codes; Reed-Solomon codes;

   Abstract : Orthogonal frequency-division multiplexing (OFDM) systems provide efficient spectral usage by allowing overlapping in the frequency domain. Additionally, they are highly immune to multipath delay spread. READ MORE
