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

摘要

In an orthogonal frequency division multiplexing (OFDM) multiple-input multiple-output (MIMO) wireless communication system where both a transmitter and a receiver include a plurality of antennas, a method comprising the steps of: a receiver using at least one pseudo noise (PN) to associate desired information relating to a received symbol; and transforming the correlated information into frequency domain.
