METHOD AND APPARATUS FOR MIMO CHANNEL ESTIMATION USING TDS-OFDM IN DOWNLINK TRANSMISSION IN THE TIME DOMAIN

摘要

In an orthogonal frequency division multiplexing (OFDM) multiple-input multiple-output (MIMO) wireless communication system, a method is provided. In the OFDM MIMO wireless communication system, both a transmitter and a receiver include a plurality of antennas. The method comprising the step of: a receiver using at least one pseudo noise (PN) to correlate desired information relating to a received symbol; and performing channel estimation using the correlated information.
