Abstract :
This paper presents a new analytical solution for the cumulative distribution function of the throughput of an adaptive MIMO-OFDM system in Rayleigh fading channels. We derive novel results on the distribution of the eigenvalues and hence compute the mean and variance of the number of bits transmitted per OFDM block. We compare the performance of the adaptive MIMO-SVD scheme with that of an adaptive modulation system employing MMSE receivers and demonstrate the effect of reduced feedback on the LTE system performance.
