Title: Radio transmission device and method
Inventor: TANABE YASUHIKO
IPC: H04J99/00
Filed: 2007-05-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a radio transmission method and device for known signal for channel estimation that can perform channel estimation with high precision by reducing interference between subcarriers.  <P>SOLUTION: The radio transmission device transmits one or a plurality of OFDM symbols for channel estimation which include a plurality of subcarriers and have temporarily independent known signal series between adjacent subcarriers. For example, the subcarriers transmitting the known signal series are different for each of the OFDM symbols, and the subcarriers transmitting the known signal series of the respective OFDM symbols are not adjacent, so that interference from the adjacent subcarries can be prevented. Further, the subcarriers transmitting the known signal series of the respective OFDM symbols are at asymmetric positions with respect center frequencies of the plurality of subcarriers as axes, so that interference from a subcarrier at a symmetric position due to Q imbalance can be prevented.  <P>COPYRIGHT: (C)2009,JPO&INPIT
