Patent ID: 6853677

Claim:
A finger comprising: an antenna signal combiner for combining signals received by a plurality of antennas and having the same time delays with an adequate delay to produce multiplexed signals; a tracking apparatus for receiving said multiplexed signals to estimate time delay information on said multiplexed signals; a de-spreading apparatus for de-spreading said multiplexed signals with said estimated time delay information, each of which are received from said antenna signal combiner and said tracking apparatus, respectively; a channel estimating apparatus for estimating channel information of said de-spread signals received from said de-spreading apparatus; and a demodulating apparatus of demodulating said de-spread signals received from said de-spreading apparatus, to estimate original signals received by said plurality of antennas, wherein said channel estimating apparatus includes a channel state estimator for receiving said multiplexed signals from said multiplexer to estimate channel information on the signals per the plurality of the antennas using a time division method, a demultiplexer for demultiplexing the output signals from said channel state estimator and a plurality of storage means for storing said demultiplexed signals from said demultiplexer, so that channel information on each of said antennas basis is estimated.
