Abstract

In space time block coded (STBC) MIMO-OFDM systems, most receivers assume the channel noise to be Gaussian, this paper considers the semi-blind detection of symbols in impulsive noise environments. Our aim is to introduce a new receiver for STBC MIMO-OFDM transmission over Rayleigh fading channels using Zernike moments. The detrimental effects of multipath on the transmitted symbols are alleviated using invariance to rotation, and scaling properties of the Zernike moments. The performance of the new method is shown in symmetric alpha-stable (SalphaS) and Middleton noise environments.
