Claim Text:
1. A method for allocating a data rate at a transmitter including a plurality of antennas, comprising: determining a reference noise threshold corresponding to a data transmission at a first data rate applied to a base layer from among a plurality of layers; determining a first modulation scheme and a first coding rate for the first data rate; determining a target noise threshold corresponding to one or more other layers from among the plurality of layers based on the reference noise threshold and whether scalable video coding (SVC) is used; allocating a second data rate corresponding to the one or more other layers, based on the determined target noise threshold; and determining a second modulation scheme and a second coding rate for the second data rate, wherein when the SVC is used, the reference noise threshold is determined such that base-layer data can be received at a receiver in a low-signal to noise ratio (SNR) channel environment, and wherein when the SVC is not used, the target noise threshold is determined such that enhanced-layer data and the base-layer data can be received at the receiver in the low-SNR channel environment.
