Improved Performance of Multiuser System Using Combined Diversity with Nagakami Fading Channel
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 3
Abstract
In wireless communication security, Signal to Noise Ratio (SNR) and Bit Error Rate (BER) are the important parameters to be improved. Frequency Hopping Spread Spectrum (FHSS) combined with Nagakami Fading Channel (NFC) and combined diversity techniques have been proposed to improve the performance of multi-user system. Combined diversity is nothing but a combination of Maximal Ratio Combining (MRC) and RAKE Receiver. Nagakami fading channel supports both line of sight and multipath communication so that it can tolerate both weak and severe fading. FHSS is used to enhance security in areas where secured communication is needed. Combined diversity technique is used to avoid fading (i.e random fluctuations in signal) and to increase the SNR. By combining these techniques one can provide secured communication with improved SNR and BER. It can be used in military areas, satellite communication. The software used to simulate the proposed method is MATLAB.
