Abstract

In this paper, average symbol error rate
(ASER) performance of rectangular quadrature amplitude modulation (RQAM) scheme
is analyzed over α-η-µ fading channels. First, an ASER expression is derived
based on Chernoff approximation of Gaussian Q-function.
Then, an asymptotic ASER formula is obtained for analyzing system behavior at
high signal-to-noise ratio (SNR) regime. The ASER performance is presented for
different modulation levels and fading parameter values. In addition, relative
truncation error (RTE) is illustrated in order to determine how many terms are
needed for the computation of proposed expression. It is shown that analytical
results are in close agreement with exact results.
