Abstract :
To combat strong multitone narrowband interference (MTNBI), a robust channel estimation method, based on the M-estimation method, is proposed for channel estimation in multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) systems. Simulation results show that the new channel estimation method in the presence of MTNBI is a promising approach.
