RADIO TRANSMITTER, RADIO RECEIVER AND SYMBOL ARRANGING METHOD

摘要

A symbol arranging method by which a processing load due to channel estimation forMIMO channels can be reduced. In the method, a symbol is arranged for a transmission frame format having a pilot area and a data area. The pilot symbol is arranged in the pilot area. An ICE data symbol used for iterative channel estimation (ICE) is arranged in an ICE data area in the data area. The MIMO data symbol not used for ICE is arranged in the MIMO data area in the data area.
