Monte Carlo Augmented Channel Estimator
URSI Radio Science Letters · 2022
We have developed a novel Monte Carlo augmented channel estimator for millimeter-wave orthogonal frequency-division multiplexing systems to better estimate and correct a transmitted orthogonal frequency-division multiplexed signal by incorporating the predefined known responses of system hardware and their errors.We compare our estimator against current channel estimators for different phased-array configurations and propagation channels.By accounting for these known responses of system hardware, our estimator provides an order-of-magnitude reduction of the standard deviation of the error vector magnitude and a reduction of the mean and standard deviation of the bit error ratio.
