Abstract
An apparatus and method for channel estimation using preamble signals received from a serving Node B and neighboring Node Bs each having N (≧1) transmit antennas in a UE having M (≧1) receive antennas in a broadband wireless communication system. In the channel estimation apparatus, a Node B number decider calculates the maximum number Nof channel-estimatable Node Bs using a preamble length, the number of antennas in each of the Node Bs, and the number of multiple paths. A multi-cell preamble matrix generator generates a multi-cell preamble matrix xby generating a Node B preamble matrix for each of the Node Bs and selecting NNode B preamble matrices according to reception power among the Node B preamble matrices. A channel estimator performs a channel estimation using xand signals received through the M antennas during a preamble receiving period.
