Summary: 
A new channel identification algorithm using both pilot and traffic channels is proposed. It is based on the linear modelling for the fading channel and takes the form of a modified recursive least-squares (RLS) algorithm. Its existence is also analyzed. It will be shown through computer simulation that the proposed algorithm is robust to the variation of the channel fade rate in a mean square error (MSE) sense.
