AbstractThis paper investigates the performance of multiple input multiple output orthogonal frequency and code division multiplexing (MIMO-OFCDM), where practical channel estimation is carried out with time-multiplexed pilot signals. Conditioned on each channel realization and estimation, the BER of MIMO-OFCDM is analytically evaluated, assuming zero-forcing successive interference cancellation (ZF-SIC) in the space domain and minimum mean square error (MMSE) detection in the frequency domain. Then, the conditional BER is averaged over all channel realizations by means of simulations. It is shown that with various channel estimation qualities and channel correlation conditions, the proposed semi-analytical approach provides precise performance estimations. ©2009 IEEE.
