ABSTRACT:
An apparatus and method of searching a preamble signal in a search window for reducing a chip size of a preamble searcher in a transceiver of a base station is enclosed. By using a plurality of small window preamble searchers searching the preamble signal in a small search window, which is a division of a large search windows of a conventional preamble searcher divided by search start times, the preamble searcher of the entire search window can be implemented and the size of semiconductor chip is reduced by implementing distributing small preamble searcher in a small semiconductor chips.
