  • Abstract
    Adaptive modulation (AM) schemes in multiinput multioutput (MIMO) systems are usually designed and analyzed under the assumption of perfect channel state information (CSI). In this paper, we consider the effect of CSI imperfection on the bit error rate (BER) and average spectral efficiency (ASE) performance. Approximate analytical expressions for BER and ASE are derived and verified by simulations. The thresholds for the CSI imperfection are identified, below which an ideally designed AM MIMO system can operate satisfactorily
