Abstract

The combination of the multi-input and multi-output (MIMO) technology and Orthogonal Frequency Division Multiplexing (OFDM) technology becomes the key technology in 4G mobile telecommunication, which can be against frequency selective fading, increase the data transmission rate and improve the system capacity. The improved RLS algorithm with the adaptive forgetting factor in time-varying MIMO-OFDM system can improve the convergence rate and mean square error (MSE). The improved MIMO-OFDM system applied in the mine communication is a new try to solve the problem of multipath fading and to improve the quality and performance in the mine communication.
