Asymptotic Performance of MMSE MIMO Systems Using Adaptive Modulation
(English)In: IEEE Communications Letters, ISSN 1089-7798Article in journal (Other academic) Submitted
This letter investigates the asymptotic performance of minimum-mean-square error (MMSE) in MIMO systemsusing adaptive modulation. The asymptotic average spectral efficiency and bit-error rate (BER) are derived basedon three approximations of the probability density function (p.d.f.) of effective SNR. Simulations suggest that themost accurate estimation of average spectral efficiency is obtained by using Gamma distribution.
