Abstract :
We propose a greedy algorithm for designing Grassmannian constellations that mimic the distribution that achieves the high SNR capacity of a noncoherent MIMO fading channel. We also introduce a reduced complexity suboptimum detector whose performance is comparable to that of the optimal detector.
