摘要：
A multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) transmission and reception apparatus is provided which allows high accuracy estimation of frequency offset, high accuracy estimation of a transmission path fluctuation and high accuracy synchronization/signal detection. A mapping section generates a plurality of OFDM signals. In these OFDM signals, some pilot carriers are assigned to the same carrier position, and orthogonal sequences are assigned to the same time slot in the same carrier position.
