METHOD FOR ENBODYING FRAME IN WIDEBAND WIRELESS COMMUNICATION SYSTEM USING MULTI ANTENNAS

摘要

A wireless communication system including multiple antennas is provided to estimate a wireless channel and allocate a resource between a plurality of users by comprising a super frame composed of a plurality of frames and the frame with a plurality of preambles. A plurality of preamble symbols are arranged(501). One signal symbol is arranged in an arbitrary position between the plurality of preamble symbols(502). At least one data symbol is arranged after the plurality of preamble symbols(503). The number of preamble symbols is larger than the number of the multiple antennas.
