Abstract

This paper presents a combined approach to channel estimation for multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM). It uses both time domain and frequency domain information in the received signal to estimate the channel. Initial estimate of the channel is obtained using pilot assisted least square (LS) channel estimation. The estimate is further enhanced by extracting information through the received data symbols. A frequency domain approach is used to estimate the channel using pilots whereas time domain approach is used to enhance the estimate of the channel. The performance of the proposed estimator is studied under various channel models. The simulation study shows that this approach outperforms the pilot assisted least square channel estimation method.
