Performance of MDPSK in Wireless Frequency Non-selective Slowly Nakagami-m Fading Channels

Abstract

In this paper symbol error rate (SER) performance of MDPSK over frequency non-selective slowly Nakagami-m fading channels is presented. The solution is in terms of single integral with finite limits and an integrand composed of elementary (trigonometric) functions. This new form of representation is simple enough for numerical computation for cases of practical interests. The final equation derived for SER is general enough so that it includes AWGN (m = ∞) and Rayleigh fading plus AWGN (m = 1) as special cases. Symbol error probability of MDPSK in Nakagami-m fading for various values of M and m is plotted and examined. The results presented are expected to provide useful information to communication systems design engineer for design and evaluation of MDPSK based radio communication link over Nakagami-m fading.

Indexing terms:

• Error probability
• MDPSK
• Nakagami fading
• Wireless mobile communication
