Abstract:
1. A set of instructions stored on a non-transitory computer readable memory that, when executed by a processor, perform a method for communicating through a multiple input multiple output (MIMO) channel, the method comprising: inputting a channel matrix and a signal-to-noise ratio (SNR) value; choosing a communications level for each of at least two modes of communication by predicting the communications level that yields an acceptable packet error rate for each of the at least two modes of communication, wherein the acceptable packet error rate is calculated as a function of the MIMO channel matrix and a signal to noise ratio (SNR) of signals received through the MIMO channel; and calculating a spectral efficiency for the chosen communications level of each of the two modes of communications and selecting one of the at least two modes of communications that has the highest spectral efficiency with the chosen communications level, wherein selecting one of the at least two communication modes includes selecting a communication mode that includes a space time block code (STBC) and the spectral efficiency of the STBC mode is expressed as: wherein SE is the spectral efficiency, c
