چکیده
Low signal to noise ratio (SNR) channels require careful design of communication systems in order operate reliably such extreme channels. Special measures and techniques must be considered when designing for environments counteract the effect high power. Channel coding is a powerful tool aid against adverse channel conditions including low SNR. Coupling with spreading technique can further strengthen performance systems. Hence, we studied system that combines Raptor codes direct sequence code division multiple access (DS-CDMA) SNR scenarios. The wide range values. Simulation results show offer satisfactory BER at different rates. Also, combining DS-CDMA showed an improvement approximately 6 dB compared other schemes using conditions.

متن کاملTarget Tracking Based on Virtual Grid in Wireless Sensor Networks
One of the most important and typical application of wireless sensor networks (WSNs) is target tracking. Although target tracking, can provide benefits for large-scale WSNs and organize them into clusters but tracking a moving target in cluster-based WSNs suffers a boundary problem. The main goal of this paper was to introduce an efficient and novel mobility management protocol namely Target Tr...
