Title:
MIMO受信装置及びMIMO受信方法
Document Type and Number:
Japanese Patent JP5002215
Kind Code:
B2
Abstract:
AMIMO-OFDM transmission apparatus is providedwhich allows high accuracy estimation of frequency offset, high accuracy estimation of a transmission path fluctuation and high accuracy synchronization/signal detection. Pilot symbol mapping (1111) is provided for forming pilot carriers by assigning orthogonal sequences to corresponding subcarriers among OFDM signals which are transmitted at the same time from respective antennas in the time domain. Even when pilot symbols are multiplexed among a plurality of channels (antennas), this allows frequency offset/phase noise to be estimated with high accuracy.
