摘要 |
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 N S of 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 x S by generating a Node B preamble matrix for each of the Node Bs and selecting N S Node B preamble matrices according to reception power among the Node B preamble matrices. A channel estimator performs a channel estimation using x S and signals received through the M antennas during a preamble receiving period. |
