摘要
Provided are a training signal generation method using impulse trains encoded with orthogonal codes and a channel estimation method using an orthogonal code decoding in a Multiple-Input Multiple-Output-Orthogonal Frequency Division Multiplex (MIMO-OFDM) system. The channel estimation method using the orthogonal code decoding in the MIMO-OFDM system includes the steps of creating a plurality of orthogonal codes depending on the number of receive antennas, decoding a signal received through each receive antenna by using the orthogonal codes, and estimating a channel response by averaging the received signals decoded with the orthogonal codes every OFDM symbol.
