Abstract :
This paper investigates a least square (LS) based multi-step autoregressive prediction filter for the delay compensation over multiple input multiple output (MIMO) channels and presents a robust adaptive MIMO-OFDM system with the filter in mobile fading channels. Computer simulation verifies that data capacity of proposed MIMO- OFDM is 20% greater than that of conventional MIMO-OFDM.
