RATE SELECTION FOR OFDM SYSTEM |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To determine a rate for a data transmission in OFDM transmission. <P>SOLUTION: The maximum data rate that may be reliably transmitted over a given multipath channel by OFDM transmission is determined based on a metric for an equivalent channel. As for the given multipath channel and a particular rate, the metric is derived from an equivalent data rate and the particular modulation scheme. A threshold SNR needed reliably to transmit the particular data rate using the particular modulation scheme and coding rate is then determined. The particular rate is deemed as being supported by the multipath channel if the metric is greater than or equal to the threshold SNR. Incremental transmission is used to account for errors in the determined data rate. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
