Performance of 2:1 MISO System in Mobile Communications

Abstract

of various modulation techniques of 2:1 antenna systems under different fading environments such as Rayleigh, Rician and Nakagami fading. It is concluded that the BIT ERROR RATE (BER) and SYMBOL ERROR RATE (SER) is least in case of QAM modulation technique as compared to the other three modulation techniques i.e.: BPSK, QPSK, 8PSK for different fading environments i.e.: RAYLEIGH, RICIAN and NAKAGAMI. In case of all the modulation techniques, for a particular value of error rate, NAKAGAMI fading gives approximately 3db more gain as compared to RAYLEIGH fading. The performance of RICIAN fading lies in between NAKAGAMI and RAYLEIGH fading. So the performance of the system is better in case of NAKAGAMI fading environment.
