Rate control for multi-channel communication systems |
摘要 |
Techniques to determine a set of rates for a set of data streams to be transmitted in a multi-channel communication system are disclosed. A group of transmission channels to be used for each data stream is initially identified. An equivalent system for each group is then defined to have an additive white Gaussian noise (or flat) channel and a spectral efficiency equal to the average spectral efficiency of the transmission channels in the group. A metric for each group is then derived based on the associated equivalent system, e.g., set to the SNR needed by the equivalent system to support the average spectral efficiency. A rate for each data stream is then determined based on the metric associated with the data stream. The rate is deemed to be supported by the communication system if the SNR required to support the data rate by the communication system is less than or equal to the metric.
