  • Abstract
    Abstract-In this paper, we investigate the performance of constant-power adaptive L-ary quadrature modulation (L-QAM) for an opportunistic decode-and-forward (DF) relaying scheme. Specifically, we adopt adaptive five-mode L-QAM with fixed and optimum switching and derive expressions for the error rate, outage probability and spectral efficiency over both independent and identical (i.i.d.) and independent and non-identical (i.n.d.) Rayleigh fading channels.
