Abstract:
A channel impulse response is determined for a channel by receiving a signal from the channel, and by determining a least squares estimate of the channel impulse response. The received signal contains a training sequence and unknown data. The least squares estimate of the channel impulse response is determined by multiplying the received signal by a stored quantity. The stored quantity is based on (i) a stored replica of the training sequence, and (ii) an assumed covariance matrix that is based on a noise variance and an initial channel impulse response that assumes a unit physical channel.
