Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of transmitting pilots, the method comprising: transmitting pilots over N orthogonal frequency division multiplexing (OFDM) symbols, wherein a pilot P n k at subcarrier k for OFDM symbol n is determined by: P n k=−7 =Ψ (n mod 2)+2 ,P n k=7 =Ψ ((n+1) mod 2)+2 ,P n k∉{−7,7} =0 wherein a OFDM symbol index n=0, . . . , N −1, pilot values Ψ 2 =1 and Ψ 3 =−1. 2. The method of claim 1 , wherein a bandwidth of…
