Abstract: A channel estimator for use in wireless local area networks (WLAN's), characterized in that a channel estimation controller with a simplified recursive least square (RLS) algorithm and a data-reconstructor are employed to adjust the channel response in frequency domain during the delivery of a signal packet. Such adjustment is adaptively performed at anytime during the delivery of a signal packet so as to achieve fast convergence as well as accurate channel estimation.
