This paper presents, an enhanced channel estimation for Spatial Multiplexing (SM) Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) system. Initial estimate of the channel is obtained using pilot assisted Least Square (LS) channel estimation using frequency domain approach. Recovered symbols are used to further enhance the channel estimate through time domain...
This paper presents a joint channel estimation and data detection (JCEDD) for multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) system. Initial estimate of the channel is obtained using semi-blind channel estimation (SBCE). The whitening rotation (WR) based orthogonal pilot maximum likelihood (OPML) method is used to obtain the channel estimate. The estimate is...
