Summary:
This paper presents a semi-blind channel estimation scheme for OFDM systems with multiple receive antennas. Using the statistical property of the received signal, we combine the pilot-based least-squares estimator with the subspace-based blind estimator. To improve the performance of the subspace-based method, we reduce the effect on the residual error which affects the accuracy of the noise subspace. Simulation results show that the proposed method is effective and improves the performance.
