PILOT MULTIPLEXING METHOD AND TRANSMISSION/RECEPTION DEVICE IN OFDM SYSTEM |
| 摘要 |
<p>A pilot multiplexing method in an orthogonal frequency division multiplexing (OFDM) system. Transmission data is transmitted by an OFDM signal using the OFDM method and pilot data is directly spread so that a spectrum spread signal obtained by the spread and the OFDM signal are transmitted by multiplexing them at the same frequency band and simultaneously or by performing time-division multiplexing. The spectrum spread signal is a CDMA signal obtained by spreading the pilot data by a predetermined spread code.</p> |
