Recently, several subspace-based algorithms for blind channel identification in zero-padded orthogonal frequency division multiplexing (ZP-OFDM) systems were introduced. These subspace-based methods are attractive because highly accurate estimate of the channel can be obtained by using only a few received blocks. However, these subspace-based methods do not work when the ZP-OFDM system has virtual...
In the last decade, several subspace-based algorithms for blind channel identification in zero-padded systems were introduced. These subspace-based methods are attractive because highly accurate estimates of the channel can be obtained by using only a few received blocks. However, they do not work when applied to the zero-padded orthogonal frequency division multiplexing systems (ZP-OFDM) with virtual...
