| 摘要 |
The present invention provides a subcarrier index coordinator for use with a multiple-input, multiple-output (MIMO) transmitter having N transmit antennas, N being at least two, wherein each employs a plurality of transmit symbols with used subcarriers. The subcarrier index coordinator includes a subcarrier index generator configured to generate a set of pilot subcarrier indices and a set of data subcarrier indices for transmission. Additionally, the subcarrier index coordinator also includes a subcarrier index formatter coupled to the subcarrier index generator and configured to arrange the sets of pilot subcarrier indices and data subcarrier indices within the used subcarriers during transmission based on the N transmit antennas and the plurality of transmit symbols.
