    Abstract: A channel estimation circuit (100) includes an input interface (110). The input interface (110) is configured to receive a plurality of pilot symbols from a communication channel. Furthermore, the channel estimation circuit (100) includes processing circuitry (120). The processing circuitry (120) is configured to generate a channel autocorrelation matrix and at least one channel cross-correlation vector. The generating of the channel autocorrelation matrix and the channel cross-correlation vector can be based on predetermined statistical information on the communication channel. Additionally, the processing circuitry (120) is configured to generate a subspace mapping for a subspace transformation based on the channel autocorrelation matrix. Additionally, the processing circuitry (120) is configured to generate a subspace transformed channel autocorrelation matrix, at least one subspace transformed channel cross-correlation vector, and a plurality of subspace transformed pilot symbols, by applying the subspace mapping to the channel autocorrelation matrix, the channel cross-correlation vector, and to the plurality of pilot symbols. Additionally, the processing circuitry (120) is configured to generate a plurality of subspace channel estimation filter coefficients based on the subspace transformed channel autocorrelation matrix and the sub-space transformed channel cross-correlation vector. Additionally, the processing circuitry (120) is configured to generate an estimate of at least one channel coefficient of the communication channel based on the subspace transformed pilot symbols and the subspace channel estimation filter coefficients. Furthermore, the channel estimation circuit (100) includes an output interface (150) configured to provide the estimate of the at least one channel coefficient.
