Abstract
A channel estimator, comprises: a receiver receives a first time-domain training sequence; a first convolution circuit generates an estimated value for the first time-domain training sequence by convoluting a second time-domain training sequence with a current channel estimation value; a first subtractor generates an error by subtracting the estimated value for the first time-domain training sequence from the value of the first time-domain training sequence; an updating circuit generates an updated channel estimation value by updating the current channel estimation value with the error; the receiver iteratively receives a next symbol of the first time-domain training sequence, the first convolution circuit, the subtractor and the updating circuit repeat their operation until completion of receipt of a last symbol of the first time-domain training sequence. The updating circuit outputs the current updated channel estimation value upon completion of receipt of a last first time-domain training sequence.
