  • Abstract
    The performance of a modulation technique which is both power and bandwidth efficient, termed nonlinearly amplified 64-state quadrature amplitude modulation (NLA 64-state QAM), is studied. To assess the effects of selective fading and/or system filter imperfections, computer simulated results are presented which show the sensitivity of the modulation technique to typical group delay and amplitude distortions. In addition to the above-mentioned results, the effects of modulator imperfections in the power level combining on the Peperformance are evaluated.
