<p>A WIRELESS COMMUNICATION SYSTEM USING PILOT ALLOCATION, METHOD AND PILOT PATTERN THEREOF ARE DISCLOSED. THE METHOD IS APPLIED FOR ALLOCATING PILOTS (112) FOR TRANSMISSION OF MULTIPLE PILOT STREAMS (1 - 8) IN A MULTIPLE-INPUT-MULTIPLE-OUTPUT (MIMO) ANTENNA SYSTEM (104, 124) USING ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING (OFDM) MODULATION. IN EMBODIMENT, THE PILOT ALLOCATION ARE APPLIED IN CONTIGUOUS FRAME STRUCTURE (50, 51), AND TWO PILOTS (112) ARE ALLOCATED FOR EACH PILOT STREAM IN FRAME STRUCTURE (50, 51) COMPRISING 18 SUBCARRIERS AND 6 OFDM SYMBOLS. THE 8 PILOT STREAMS (1 - 8) ARE GROUPED INTO TWO PILOT STREAM CLUSTERS, AND PILOTS (112) FOR EACH PILOT STREAM CLUSTER ARE GROUPED INTO TWO PILOT CLUSTERS. FOUR PILOT CLUSTERS ARE THEN ALLOCATED IN FIRST FRAME STRUCTURE (50), AND THE ALLOCATION OF THE PILOT CLUSTERS IN SECOND FRAME STRUCTURE (51) CORRESPONDS TO THOSE IN FIRST FRAME STRUCTURE (50). THEREFORE, BETTER TRANSFER RATE IN SUCH WIRELESS COMMUNICATION SYSTEM CAN BE ACHIEVED.</p> |
