| 摘要 | A method of transmitting pilots id disclosed. The method of transmitting pilots includes transmitting pilots over N orthogonal frequency division multiplexing (OFDM) symbols, wherein a pilot at subcarrier k for OFDM symbol n is determined to have time varying characteristic, thereby to prevent the cause of spectral lines. | ||

| 主权项 | 1. A method of transmitting pilots, the method comprising: transmitting pilots over N orthogonal frequency division multiplexing (OFDM) symbols, wherein a pilot Pnk at subcarrier k for OFDM symbol n is determined by: Pnk=−7=Ψ(n mod 2)+2,Pnk=7=Ψ((n+1) mod 2)+2,Pnk∉{−7,7}=0 wherein a OFDM symbol index n=0, . . . , N −1, pilot values Ψ2=1 and Ψ3=−1. | ||
