    An Approximate Error Expression for RQAM Scheme under ?-?-µ Fading Conditions
    (2019) Kapucu, N.
    In this paper, average symbol error rate (ASER) performance of rectangular quadrature amplitude modulation (RQAM) scheme is analyzed over ?-?-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.

    Error Analysis of Dual-Branch SIMO Systems over ?-? Fading Channels
    (Institute of Electrical and Electronics Engineers Inc., 2020) Bilim, M.; Kapucu, N.
    In this work, error performance of dual-branch single-input multiple-output (SIMO) systems is analyzed over -u fading channels. An analytical expression is derived by using Chernoff approximation for the error probability of the considered system. Then, an asymptotic error expression is also proposed for the considered system. The results obtained from the derived expression are presented in comparison with exact results. Numerical results are shown for different configurations in order to analyze the effects of different values of fading parameter, antenna number and modulation type. In conclusion, it is observed that the approximate results are close to the exact results. © 2020 IEEE.
