Genetic algorithms are successfully used for decoding some classes of error correcting codes, and offer very good performances when solving large optimization problems .This article introduces a new Decoder based on Genetic Algorithm and the Syndrome Weight decision (GADSW) for decoding Low Density Parity Check (LDPC) codes. The performances of (GADSW)(More)
This work reports on a characterization of the ultra wideband (UWB) outdoor channel based on a channel measurements over a frequency bandwidth of 9 GHz from 3 GHz to 9 GHz. Frequency domain measurements were conducted for line-of-sight (LOS) scenario. Firstly, obtained data measurement are characterized in terms of power distribution in both time and(More)
Minimizing the total power consumption required for vertical handovers in 4th generation heterogeneous wireless networks is as important as providing users with the best QoS(Quality of Service) continuously. This letter proposes a vertical handover scheme to minimize the total power consumption required for a vertical handover in 4th generation(More)
