Abstract
A signal reception apparatus of an orthogonal frequency division multiplexing (OFDM) communication system using a multiple input, multiple output (MIMO) scheme. The signal reception apparatus, when it uses the Nreceive antennas, receives a time-domain preamble signal transmitted by a signal transmission apparatus corresponding thereto via each of the Nreceive antennas, and estimates a channel according to a channel estimation scheme using the time-domain preamble signal received via each of the Nreceive antennas. When the signal transmission apparatus uses Ntransmit antennas, the time-domain preamble signal is a signal transmitted by the signal transmission apparatus via each of the Ntransmit antennas for a second time period which is set according to a corresponding transmit antenna within a first time period.
