Robust channel estimation for OFDM wireless communication systems - an H∞ approach.

In this paper, the joint time-frequency domain channel estimation problem in orthogonal frequency-division multiplexing (OFDM) wireless communication systems is transformed to a set of independent time-domain estimation problems. A robust channel estimation algorithm based on the H∞ filtering approa...
