Abstract:
1. A method of performing rate selection for data transmission over a plurality of transmission channels in a communication system, comprising: obtaining a signal-to-noise ratio (SNR) estimate for each of the plurality of transmission channels; determining a total SNR margin for each of a plurality of rate combinations based on the SNR estimates for the plurality of transmission channels, wherein each rate combination is associated with a specific number of the data streams to transmit, a specific rate for each data stream, and a specific overall throughput and wherein the plurality of rate combinations comprise at least two rate combinations associated with the same number of data streams to transmit but different combination of specific rates for each data stream; and selecting a rate combination from among the plurality of rate combinations based on total SNR margins and overall throughputs for the plurality of rate combinations, wherein selecting a rate combination comprises selecting a rate combination having a highest overall throughput among the plurality of rate combination and selecting a rate combination having fewer data streams if multiple rate combinations have the highest overall throughput.
