1. An apparatus for rate selection in a wireless communications system comprising:

  • at least one processor configured to obtain at least one SNR estimate for a data stream, to determine a diversity order for the data stream based on a number of data streams being transmitted and a number of receive antennas, to determine an SNR variance for the data stream, and to select a rate for the data stream based on the at least one SNR estimate, the diversity order for the data stream, and the SNR variance for the data stream; and

    a memory coupled to the at least one processor.
