Fading

Abstract
This paper presents an alternative method for determining exact expressions for the bit error probability (BEP) of modulation schemes subject to Nakagami-
fading. In this method, the Nakagami-
fading channel is seen as an additive noise channel whose noise is modeled as the ratio between Gaussian and Nakagami-
random variables. The method consists of using the cumulative density function of the resulting noise to obtain closed-form expressions for the BEP of modulation schemes subject to Nakagami-
fading. In particular, the proposed method is used to obtain closed-form expressions for the BEP of 
-ary quadrature amplitude modulation (
-QAM), 
-ary pulse amplitude modulation (
-PAM), and rectangular quadrature amplitude modulation (
-QAM) under Nakagami-
fading. The main contribution of this paper is to show that this alternative method can be used to reduce the computational complexity for detecting signals in the presence of fading.
